Premiumfahrzeuge seit 1980.


Upon request we are happy to provide our premium cars with the DEKRA Seal certificate. A DEKRA expert will conduct an objective, independent inspection according to strict quality criteria. We guarantee that these criteria will be adhered to. 

DEKRA list and describe the DEKRA Seal quality criteria as follows:*

Testing reveals defects and damage

Our experts only issue a vehicle with the DEKRA Seal for pre-owned vehicles when it has met certain minimum standards in various component groups. This gives you an objective report on the quality and condition of the vehicle – defects and necessary repairs are outlined in the test documentation.

Even if a vehicle does not meet the criteria for the DEKRA Seal for pre-owned vehicles and thus cannot receive a certificate, the test report gives both purchaser and seller a neutral assessment of the condition of the vehicle.

The following 8 component groups on the vehicle are subject to the quality criteria in the DEKRA Seal for pre-owned vehicles. If the test involves a truck, motorcycle and leisure/travelling trailers, the test points are expanded as necessary, e.g. the driver’s cabin of the truck or the dampness in a caravan.

The seal requires the following criteria to be fulfilled:


  • The body parts are not restricted or defective in their function.
  • No residual traces of an accident can be detected.
  • There are neither dents or bulges or other large areas of damage.
  • No strong signs of corrosion damage or impact damage.
  • The paintwork does not display obvious signs of stone chipping damage, or large scratches that reveal bare metal.
  • The paint finish has been professionally applied (differences in colour tone).
  • Add-on parts must not be missing or severely damaged.
  • The screens must not require renewal.


  • The tester should detect no odours in the interior that could be deemed highly unpleasant.

  • The amount of anti-freeze in the coolant must at least comply with the manufacturer's recommendations.
  • The exhaust must not display severe damage and functional damage.
