Owner photographing a vehicle to request a valuation

Buying vehicles from private sellers

You are selling a personal car. Our job is to make that simple, quick and free of legal risk for you.

Built around the situations we see most

Most of the sales we handle come down to a handful of recurring situations: changing car without a dealer part-exchange, leaving Luxembourg at the end of an assignment, an estate, a separation, or simply a car that is no longer used while insurance and tax keep running.

In each of those cases the decisive factor is not squeezing out a few hundred euros more, but closing cleanly and quickly, with written evidence and a traceable payment.

Questions from private sellers

I am leaving Luxembourg in two weeks — is that feasible?

Yes, this is a common case. Flag it in your request: we prioritise these files and can usually inspect within a few days.

The car belongs to an estate. What is needed?

A certificate of inheritance and the written agreement of the heirs, plus the registration document. We confirm the exact list based on the country of registration.

I only have one key. Is that a problem?

Not a blocker, but it affects the offer: ordering a coded replacement key is a real cost that varies by brand.

My car is over fifteen years old. Can you still buy it?

Yes. Age alone is not an exclusion criterion. Mechanical condition, history and demand for the model matter more.
