FAQ
Frequently asked questions
How much does a report cost?
If the accident was not your fault, the other party’s insurer usually pays the assessor fees (exceptions e.g. for minor damage). For valuations and pre-purchase inspections, fees depend on the effort involved. For exotic & collector cars and lease returns we are happy to provide an individual quote.
Why do I need a lease return report?
Without an independent report, lessors often have the upper hand at the return and sometimes rate damage higher than justified – which can quickly become expensive. With our report you have a documented basis and only pay what is actually justified.
Do you also come to Switzerland?
Yes, we work on site throughout Germany and all of Switzerland. On request we also prepare valuations for use in other European countries, such as the UK.
How quickly will I receive my report?
Standard: usually 24–48 hours after the inspection. Express: on request in under 12 hours after the inspection – by arrangement and subject to availability, possibly for a surcharge. The period starts once the vehicle has been inspected and all documents are available. We usually reply to enquiries on the same working day.
What is a thermal camera inspection?
With a professional thermal camera we reveal moisture damage, hidden repairs and structural problems that cannot be seen with the naked eye.
Do I have to accept the insurer’s assessor?
No. You have the right to your own independent assessor. If the accident was not your fault, you can usually choose the assessor freely.
Can you also assess electric and hybrid vehicles?
Yes, we assess all electric and hybrid vehicles – from Tesla, Mercedes EQ, BMW i and VW ID to BYD, Polestar and plug-in hybrids such as the Porsche Cayenne E-Hybrid or Ferrari SF90. Particularly important: assessing the high-voltage battery after an accident.
What is legal expenses insurance and do I need it?
Motor legal expenses insurance covers the costs of lawyers, reports and court proceedings if you need to enforce your legitimate claims after an accident.
