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.

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.
