Used cars – cutting through the jungle

Used cars – cutting through the jungle

  • Keep an eye on additional costs: do not look at the purchase price alone
  • Worthwhile: take time to prepare and gather information
  • Sensible: a thorough check including an extensive test drive – especially
    when buying from private sellers

The selection is huge: dedicated used-car portals offer millions of cars of all classes, powertrains, model years and price categories. In this jungle, it is not easy to find the right car. GTUE Gesellschaft für Technische Überwachung mbH provides some tips for buying a used car. They are aimed at those looking to buy their first car, as well as those who need one every few years. Before starting the search, prospective buyers should define how the vehicle will be used, plan the budget realistically and then compare vehicles. Buying from a dealer offers more security, but is generally a little more expensive than purchasing a daily driver from a private seller.

Where should the journey go? Whether you are highly enthusiastic about the car or not, the first step before buying should be to check how and where the new vehicle will be used. Mainly in city traffic, or is the commute to work more on country roads? Will the whole family sometimes travel with shopping or luggage for the annual holiday? Comparison tests in trade magazines provide good criteria for making an initial selection.

Budget planning: Before purchasing, you should take stock not only of the purchase price itself. How high are the follow-up costs such as tax, insurance and servicing? It is also sensible to set aside a small reserve for unexpected repairs or fixing a minor parking scrape. Major accident damage is covered by the motor insurance, provided that comprehensive cover (“fully comprehensive”) has been taken out. The calculation should also include average fuel or electricity consumption. The price jumps at the pumps in recent weeks have brought this aspect more sharply into focus. Energy costs can vary considerably from vehicle to vehicle. A large sedan may sometimes consume twice as much as a small car. In terms of costs from purchase through to energy expenses, electric cars have recently become significantly more attractive.

Comparing pays off: As confusing as online portals may seem with their seemingly inexhaustible range, they do offer some advantages: almost any listing can be compared with another. With just a few clicks, you can find out whether the car offered nearby is priced within a reasonable range. This knowledge strengthens your negotiating position with the seller. The wide selection also means that many preferences for colour or equipment can be met.

Technical check: It is obvious: the cheaper a vehicle is offered, the higher the mileage and the more intensively it has been used. For a layperson, it is not easy to make a reliable judgement. A current roadworthiness inspection passed “without defects”, as offered nationwide by GTUE, is always helpful. This should rule out defects, for example in the brakes, suspension components or lighting system. If documents in the glove compartment or invoices show that all services were carried out at the appropriate times, this also builds additional trust. For electric cars, a battery test is advisable to determine its condition (“State of Health”, SoH). Anyone who can call on an expert among family or friends to help with a thorough inspection is fortunate—someone who may even spot hidden defects such as accident damage. For other buyers with little experience, investing a few hundred euros in an expert appraisal can pay off.

Test drive: A test drive is strongly recommended despite the roadworthiness inspection and plenty of documentation. How does it start with a cold engine? Does it run smoothly straight away and without an “oil plume” from the exhaust? Does the handling feel flawless or “vague”? How does the candidate behave when accelerating, braking or steering? Do all gears engage easily and without grinding noises, especially when downshifting? Does the engine sound calm and confidence-inspiring even at higher revs? Do no warning lights indicate current faults? The air conditioning should also be tested.

Where to buy? Vehicles from private sellers are generally a little cheaper, but in most cases they exclude any warranty. The seller is liable at most if they deliberately conceal technical defects or accidents, or provide false information—for example due to a manipulated odometer. Car dealers have a statutory warranty obligation when selling to private customers. Large dealerships and authorised dealers tend to offer more reliable vehicles. However, particularly low-priced offers are rather rare with them because they shy away from the risks of older vehicles or those with heavy signs of wear. Independent master workshops that specialise in a particular brand or model can be interesting. They often fix minor defects before the sale and quickly address other issues afterwards as well. In the broad field between private sellers and brand-authorised dealers, there are also, of course, the “gravel-lot” or “flag” dealers, as they are casually called. A colourful range of vehicles is on offer here, mostly in the lower price segment, including some exotics. A thorough check including a test drive, as with a private seller, is also advisable here.

These tips significantly reduce the risk when buying a used car: anyone who takes their time, reviews offers critically and seeks professional advice when in doubt can find a suitable and reliable vehicle from the huge selection.

Buying a motorhome? What to consider.

Buying a motorhome? What to consider:

+ Choose a vehicle that matches your driving licence category
+ The driving characteristics usually differ significantly from those of a passenger car.
+ Permissible gross vehicle weight, traffic rules and periodic technical inspection

Camping has been a major trend in recent years. One question often sparks debate: caravan or motorhome? Arguments in favour of a camping trailer include the lower purchase price and the fact that the towing vehicle can be used for excursions at the destination. The motorised camping vehicle, on the other hand, scores with better manoeuvrability and greater flexibility for overnight stays en route. The statistics clearly favour the motorhome: more than one million motorhomes currently registered in Germany exceed 780,000 caravans (as of 2025). Whether a minibus conversion, panel van, semi-integrated or fully integrated model: what should you consider when it comes to motorhomes? GTUE Gesellschaft für Technische Überwachung mbH provides an overview.

Driving licence
All of the vehicle types mentioned are open to anyone who holds the former Class 3 driving licence. This was issued until December 31, 1998. It allows you to drive any vehicle with a maximum gross vehicle weight of up to 7.5 tonnes. That already covers a lot. However, there are even larger motorhomes based on trucks or buses. These not only require a substantial budget to purchase, but also a truck driving licence. Anyone who obtained a Class B driving licence after January 1, 1999 may drive vehicles with a permissible gross vehicle weight of 3.5 tonnes. Good to know: the driving entitlement can be upgraded. With Class C1, vehicles up to 7.5 tonnes may be driven. This can be renewed every five years upon presentation of a health and eye examination.

Try it out and visit trade fairs
Some camping newcomers are quick to buy a vehicle. However, it is by no means a bad idea to rent the vehicle of choice, or a similar model, first. This allows you to try out living on four wheels and driving. After this real-world test, some people adjust their choice and perhaps opt for a larger motorhome if the space in a panel van does not quite meet expectations. Or the other way around, towards a smaller vehicle because it is simply more manoeuvrable. Visiting major camping trade fairs is also helpful.

Converted minibus
A converted minibus drives most like a passenger car and is also agile in the city or when looking for a parking space. The larger the vehicle, the more its characteristics change. For example, a large motorhome generally accelerates significantly more slowly than a passenger car, and the braking distance can be considerably longer. Relaxed, anticipatory driving is important—something motorhome pros already see as part of slowing down and as a plus for a holiday on four wheels.

Full-size motorhome
A full-size motorhome is not exactly nimble. You therefore always need to keep the overall dimensions in mind to avoid getting caught on the side in tight bends or on top in low underpasses. When pulling out, the often generous “blind spot” must be taken into account. When reversing, a second person to guide you is essential—and a reversing camera is also useful.
A driver safety training course is always a good idea. There you learn to control the vehicle better in tricky situations, such as evasive manoeuvres or emergency braking. Special navigation systems that take vehicle dimensions into account when planning routes are also useful. This helps avoid, for example, very narrow roads or low underpasses. Of course, this does not remove the obligation to still pay attention to the relevant traffic and information signs, as not all critical points are precisely recorded in digital road maps.

Loading and gross weight
When loading your holiday equipment, always keep an eye on the permitted gross vehicle weight. If, for example, the motorhome has an unladen weight of 2,900 kilograms with all fixtures and optional equipment and may weigh a maximum of 3,500 kilograms, then 600 kilograms are permitted. Since a motorhome cannot be driven without a driver, 75 kilograms are already included in the unladen weight. Every additional person counts as extra weight. If, for example, three people and a dog plus the family’s full travel luggage are added, 600 kilograms of payload is no longer quite so generous. If you exceed the permitted gross vehicle weight, fines are due, which in some countries can reach substantial amounts in the four-digit range. Before weighing each item individually when loading: ideally, drive the fully packed motorhome onto a vehicle scale. These are often available nearby, for example at building materials dealers or waste disposal companies.

Traffic rules
Which traffic rules apply to motorhome drivers? Here are a few examples: Up to a permissible gross vehicle weight of 3.5 tonnes, the same speed limits apply as for passenger cars. With a permissible gross vehicle weight of up to 7.5 tonnes, the maximum speed outside built-up areas and on expressways is 80 km/h, and 100 km/h on motorways. With a gross vehicle weight over 7.5 tonnes, the limits for trucks apply: 60 km/h outside built-up areas and 80 km/h on expressways and motorways. Some signs also apply to motorhomes: if trucks are subject to a through-traffic ban, an overtaking ban or a minimum distance requirement, this also applies to motorhomes over 3.5 tonnes. Less common are a through-traffic ban for trucks of a certain length, which is indicated on the traffic sign, or for vehicles with a higher axle load than indicated on the sign. These restrictions naturally also apply to motorhomes with these characteristics.

Periodic technical inspection (HU) – gas inspection
Motorhomes are, of course, also subject to the obligation to undergo regular periodic technical inspections (HU) in accordance with Section 29 of the German Road Traffic Licensing Regulations (StVZO), including an emissions test. GTUE test centres welcome camping enthusiasts—and it is not uncommon for a lively conversation to arise about the most recent holiday trip with the vehicle. A motorhome up to 3.5 tonnes is treated like a passenger car. If it is new, the first HU is due after three years. After that, it must undergo HU every two years. For motorhomes from 3.5 to 7.5 tonnes, the first periodic technical inspection is due no later than after two years. After that, the vehicle must also be presented for HU every two years. From the sixth year onwards, the inspection is due annually. Motorhomes with a permissible gross vehicle weight of more than 7.5 tonnes must always undergo the periodic technical inspection once a year.

Many motorhomes have gas-powered appliances on board, such as a cooker or heater. The gas system must be checked for leaks every two years. The gas inspection does not have to be carried out together with the periodic technical inspection, although this is often the easiest option. GTUE test centres are also equipped for this.

Towing a Trailer: Reaching Your Destination with Composure

Towing a Trailer: Reaching Your Destination with Composure

• Special regulations and characteristics of the combination
• Practice makes perfect when reversing and maneuvering.
• Driver’s license requirements must be observed.

A trailer has been purchased? Perhaps even a large one—a caravan? This marks the beginning of a new chapter in driving. By coupling the trailer, the flexible passenger car becomes a far less maneuverable combination. This combination is subject to its own rules—both legally and practically. GTUE Gesellschaft für Technische Überwachung mbH provides several tips on what to observe.

The most important advice is: Approach the matter calmly. This begins with coupling. All steps must be carried out carefully: connecting the trailer hitch to the ball head on the car and closing the anti-sway coupling, if present. Always insert the electrical cable. Sometimes an adapter is necessary. Is the breakaway cable looped around the coupling? Finally, check everything once more. Only then is the connection reliable overall and the trailer cannot jump off the ball head—this has actually happened.

Safe coupling also includes the mandatory test of all rear lights on the trailer. In addition, the car’s tires must be inflated to the correct pressure for trailer operation. The relevant data is provided in the operating manual. Is the jockey wheel raised and locked in this position? Are the additional exterior mirrors mounted for oversized trailers? Have the wheel chocks been removed from the road? If all these questions can be answered with “Yes,” the journey can begin.

At this moment, the experienced driver mentally switches to a different mode: they are essentially controlling a completely different vehicle than usual. For the inexperienced, it helps to keep this in mind repeatedly. From this moment on, they acknowledge the combination’s characteristics. Anticipatory driving is even more important than usual. The combination is longer, wider, and higher than the solo car, especially with caravans. The noise environment is different. Wider turns must be taken in curves. It is absolutely necessary to keep an eye on oncoming traffic. When overtaking, more space is needed for pulling out and merging back in than usual. The blind spot requires particular attention. When accelerating, the combination responds more sluggishly to the accelerator. The braking distance is longer. Here too: When driving a combination, composure helps. Hasty actions are out of place.

Are you going on vacation with the caravan? Then you should definitely plan sufficient breaks. In addition, the average speed is significantly lower than with a solo car. Therefore, the family should expect a journey time 30 to 50 percent longer.

Route planning also requires care. Does the initially selected route include extreme inclines and declines or very narrow roads? Sometimes it is more pleasant to avoid such sections and accept a route that is a few kilometers longer. Navigation systems help increase safety. There are solutions, including mobile apps, that consider not only the lower driving speed but also the combination’s dimensions when calculating the estimated arrival time. They recommend only suitably appropriate routes.

Reversing and maneuvering are a real challenge for beginners with a trailer. The rear of the trailer moves in the opposite direction to the steering movement of the towing vehicle when reversing. A short practice session in an empty parking lot provides some routine. Modern vehicles have built-in maneuvering assistants that can be a great help. A spotter is indispensable, who also warns rearward traffic. Anyone who feels uncertain can take a few additional driving lessons. Alternatively, a special driver safety training course can be completed, as this usually includes maneuvering as well.
Regarding legal aspects: In Germany, combinations may travel at a maximum of 80 km/h outside built-up areas. This also applies to the motorway, unless the trailer has a 100 km/h approval. The slightly higher speed allows overtaking trucks. However, caution is advised at higher speeds, as the trailer can react sensitively to crosswinds. Different speed limits often apply abroad: It is best to inform yourself beforehand so that no fine burdens your travel budget.

On the road, attention must be paid to special traffic signs. For example, there is an overtaking ban for combinations, indicated by a symbolically depicted car with a trailer. Less common is the prohibition sign for long vehicles. It shows a truck and specifies the relevant length, which then also applies to combinations. Other signs warn of narrow passages or low clearance heights. Using a cheat sheet attached to the dashboard containing information on the combination’s length, width, height, and weight allows you to see at a glance whether passage through a bottleneck is possible.

Special regulations also apply to parking. Some examples: – If a registered trailer is parked at the roadside without a towing vehicle, it may remain in this location for a maximum of two weeks. If it is coupled to a towing vehicle, there is no time limit. However, it must be a parking space that is not designated exclusively for cars. A combination may not be parked there. Trailers weighing up to 2.8 tons may be parked on the edge of sidewalks if traffic signs permit this. The corresponding markings must not be exceeded. If the trailer is heavier, it must be parked in a truck parking area.

Finally, regarding the driver’s license. Those who acquired it before 1999 are in a good position. With the former Class 3, the driver may operate three-axle combinations with a total weight of 12 tons. It is different with Class B: With it, the trailer may weigh a maximum of 750 kilograms. Class B can be extended without an examination and usually through a one-day course with the B96 addition to tow heavier trailers. In both cases, with or without B96, the weight limit for the complete combination is 4.25 tons. Quick calculation: If the towing vehicle weighs 2.2 tons, for example, 2.05 tons remain for the caravan. Both apply to the fully loaded and ready-to-drive condition. This should be sufficient for many cases. Alternatively, the driver’s license can be extended to Class BE, then the total combination may weigh seven tons. A look at motorhomes: With a Class B driver’s license, it may weigh a maximum of 3.5 tons. For a weight of up to 7.5 tons, Class C1 is required. This driver’s license is valid for a limited period. After five years, a medical certificate of fitness and a current eye test must be submitted for renewal.

First time for the periodic technical inspection – safety and environmental protection

First time for the periodic technical inspection – safety and environmental protection

For new drivers, many things are new. Including the first trip to the periodic technical inspection (HU) with your own car. GTUE Gesellschaft für Technische Überwachung mbH offers it nationwide at its test centres in Germany. It is a mandatory inspection: the legislator has designated it as such to make road traffic safer and to ensure a high standard of environmental protection. The inspection organisation explains how to pass the HU on the first attempt and make it as pleasant as possible.

Very convenient: GTUE makes the periodic technical inspection as pleasant as possible. Flexible appointment scheduling helps enormously, and on the day itself you simply drive up and hand in the car keys and Registration Certificate Part I (“vehicle registration document”) at reception. After that, you can make yourself comfortable with a cup of coffee and browse through the magazines on display. Registration Certificate Part II (“vehicle title”) is not required. The inspector does not ask about driving skills – they only carry out a technical check of the car.

Some allow the customer to be present in the inspection hall – it is best to simply ask. And the expert will of course also appreciate a clean car.

The basic facts: The expert’s first step is to match the vehicle identification number (VIN) on the chassis with the data in the registration document. Do the licence plate and HU due dates also match all the information provided?

Not too late: The HU appointment must not be significantly overdue. When the inspection is due can be seen from the sticker on the rear licence plate or from the entry in the registration document. The sticker is applied so that the due month is at the top; the year can be found in the middle. From two months late, an extended HU is required and higher inspection costs apply.

Braking system: It takes around half an hour for GTUE inspection engineers to thoroughly examine the vehicle according to a prescribed scheme. A key objective of the periodic technical inspection is road safety. Take brakes, for example: they must function reliably on every vehicle. On the roller brake tester, GTUE professionals determine the braking force of each individual wheel, as well as the brake force distribution between wheels and axles. Accident risks lurk: if the relevant limit values are not met, the stopping distance can be significantly longer or the car can skid. The condition of brake discs and brake lines is also checked. All results are recorded in the inspection report and are easy to understand.

View from below: The check of steering and suspension also serves safety. For this, the car is placed on a lift and viewed from below. Do the front wheels respond directly to steering movements? Or with a slight delay, i.e. with “play”? Tie rods, tie-rod ends, the steering gear, as well as boots and seals are also checked. On older vehicles, corrosion can impair the function of some suspension components.

Clean air: If all exhaust aftertreatment systems of petrol and diesel engines are optimally adjusted and function perfectly, the environment, air quality and health benefit. Smoke plumes from the exhaust are rare thanks to modern engines with fuel injection systems and catalytic converters.

Whether all settings are correct and the vehicle complies with the applicable emission limits is determined by the emissions test (AU) using diagnostic equipment. It is an integral part of the periodic technical inspection and in many cases is carried out via a probe in the exhaust. Some vehicles store their own limit values via on-board diagnostics; the inspection engineer reads this data via a connector and checks engine settings, catalytic converter and particulate filter for defects.

Communication: Is the periodic technical inspection complete? Some people are not interested in how the inspection engineer proceeds in detail. Others are all the more interested. Gladly: many GTUE inspection engineers are happy to explain the inspection result.

Perfect condition: In most cases, the overall verdict is “no defects found”. The inspection engineer returns the vehicle with a new sticker on the rear licence plate, and the registration document receives a new stamp. The customer receives the detailed inspection report – and drives off with the good feeling of being at the wheel of a thoroughly inspected vehicle.

Minor fixes: If the conclusion is “minor defects”, the inspection engineer has identified small issues that do not directly endanger road safety. These can be worn wiper blades or slight oil dampness on the engine, transmission or rear axle. They note these faults in the inspection report. To stick with these examples: it then makes sense to replace the wiper blades and to watch out for whether oil spots can actually be seen under the vehicle at some point. In that case, a repair is usually advisable before major damage occurs.

A bit more: Not a disaster, but still annoying, is the verdict “major defects” on the inspection report. In that case, road safety or environmental compatibility is impaired. The listed defects must be remedied within four weeks; then the car may return to the test centre for a simplified re-inspection at lower fees. Otherwise, everything starts again from scratch with a complete periodic technical inspection.

Rejected: Only rarely does it come to the extreme case with the verdicts “dangerous defects” or “unroadworthy”. In this case, the vehicle may no longer participate in road traffic until the defects have been remedied.

Such a drastic verdict is possible, for example, if brake lines are leaking or a wheel can no longer be properly secured.

GTUE tips for a pre-check: Very many “major defects” can be avoided with simple checks that anyone can carry out themselves within 15 minutes. Do all lights work, including reversing lights and hazard warning lights? Against a wall at dusk or at night, you can quickly see whether a headlight is shining correctly forwards or strongly upwards, downwards or to the side. Do all tyres have sufficient tread? Does the horn work? Are a high-visibility vest, warning triangle and first-aid kit on board? GTUE provides checklists with detailed information on what motorists can check themselves. Here is the link: https://www.gtue.de/de/gtue/publikationen/checklisten/fuer-pkw. If you prefer more convenience, have a workshop carry out the pre-check. A trip to the professionals is essential if warning lights stay on permanently, indicating faults in, for example, the anti-lock braking system, cooling system or engine.

Statistics prove the importance of the HU: GTUE carries out many millions of periodic technical inspections year after year. The data shows how useful a periodic technical inspection is. A tiny excerpt: in 2025, GTUE inspected almost two million vehicles up to twelve years old with different types of powertrain. More than 160,000 of them did not receive a new sticker after the initial inspection due to “major defects”. 60,000 of these vehicles were refused the sticker due to worn brake pads and worn brake discs. Damaged brake discs also rank high in the defect statistics for inspected vehicles with purely electric drive (BEV) and plug-in hybrids (PHEV).

Better to check beforehand: Regardless of the type of powertrain, tyres are also frequently criticised, usually due to insufficient tread, damage, or because they are not approved for the vehicle. GTUE inspectors also note incorrectly adjusted dipped headlights strikingly often – a “major defect” that can, of course, be easily avoided before the trip to the test centre with the right expert adjustments.

 

  • Whether new driver or experienced: the HU is usually done after 30 minutes and a cup of coffee
  • Before visiting the test centre, it is best to check the lights and tyres yourself
  • Defect grading depending on the vehicle’s weak points
  • Brakes are criticised particularly often by inspection engineers

Spring – A clean car improves road safety

Spring – A clean car improves road safety

Away with winter! Tips from GTUE Gesellschaft für Überwachung mbH: Salt and dirt can promote corrosion and stress components. For better visibility and recognition, windows, wipers, and lights should be cleaned and checked. Act environmentally responsibly: Use suitable washing locations, dose agents sparingly, dispose of residues correctly.

For many drivers, the first mild days of spring mean a thorough spring cleaning for their car. After months of wet weather, road salt, and dirt, a thorough cleaning is more than just cosmetic: it preserves the car’s substance and can increase road safety. Clear windows, well-functioning wipers, clean lights, and a dry interior directly impact visibility, recognition, and operability. Those who pay attention to suitable washing locations and appropriate cleaning agents combine care with environmental protection.

Clean the interior

Start with the interior: Floor mats and carpets absorb a lot of moisture in winter – and with it, salt and dirt. Thorough vacuuming, removal of residues, and drying wet mats reduce the risk of fogged windows and unpleasant odors. For dashboards and plastic surfaces, slightly damp microfiber cloths are often sufficient. Aggressive shine sprays are usually not necessary for proper cleaning. During pollen season, it may also be advisable to check the cabin air filter, as a dirty filter reduces air quality and promotes fogged windows.

Clean the exterior

For the exterior, a systematic approach is also recommended. A pre-wash loosens coarse dirt and the typical winter film. Afterwards, paint and glass surfaces can be cleaned more gently, as fewer particles are dragged across the surface. Important areas are wheel arches and rims. Brake dust and salt residues accumulate here, which can attack the material. Door sills, entryways, and seals also deserve attention, as dirt and moisture can settle there. Economical care of rubber seals keeps them supple and reduces squeaking noises.

Windows, mirrors, and lighting are particularly important

For road safety, windows, mirrors, and lighting are particularly relevant. Streak-free front and side windows improve visibility, which is especially important when the spring sun is low. Note: Cleaning is not only done on the outside but also on the inside. During the winter season, the windshield ventilation runs particularly frequently, and fine particles settle on the glass. Wiper blades should be cleaned and replaced if streaking occurs. Lights and reflectors must be clean so that the vehicle is clearly visible. Additionally, a quick technical check is worthwhile: Does the windshield washer system work? Is there enough cleaning fluid? And are tire tread and pressure within a safe range? Such checks also correspond to the logic of the general inspection, as carried out by the GTUE. While cleanliness does not replace an inspection, it can help to detect abnormalities such as damage, corrosion, or leaks early on.

Sustainability in vehicle cleaning

Sustainability begins with the “how” and “where.” For environmental reasons, cleaning in a car wash or at a designated washing area is better than cleaning by the roadside. There, wastewater is typically controlled, discharged, and treated so that it does not enter the soil and water uncontrolled. For cleaning agents: Concentrates and refill systems save packaging material and transport volume. The dosage is also crucial, because too much cleaner burdens the wastewater and the wallet without improving the cleaning result.

Disposal is also part of sustainability. Cleaner residues, polishes, antifreeze, or heavily soiled cloths do not belong down the drain or in the toilet. They should be collected and disposed of correctly according to local regulations via the recycling center or hazardous waste collection. Empty containers can – depending on the material – be placed in the designated recycling systems. This way, spring cleaning is not only thorough but also responsible.
