Selling a car quickly involves several thousand francs — and legal responsibility. We see these seven mistakes again and again in practice. Knowing them means selling faster, more safely and at a better price.

Mistake 1: Unrealistic price expectations

The most common error: the asking price is based on what you once paid, or on the most expensive listings. The result is months without serious enquiries — while the car keeps losing value. Better: research actual sale prices of comparable vehicles and get a professional valuation.

Mistake 2: Missing or incomplete documents

No service booklet, only one key, no MFK report: every gap lowers the price and raises suspicion. Gather all documents before selling — including invoices for major repairs. A complete record can mean several hundred francs more.

Mistake 3: Concealing defects

Concealing known defects or accident damage risks contract rescission and damages — sometimes years after the sale. Honesty is not just a legal duty; it also speeds up the sale: transparent offers attract serious quotes faster.

Mistake 4: Expensive repairs before selling

New brakes, a fresh service, repainting scratches — "so it sells better"? You almost never recover these investments in the sale price. Dealers and buyers price repairs at wholesale rates; your as-is price plus the saved repair costs usually beats the post-repair proceeds.

Mistake 5: Accepting unsafe payment methods

Cheques, payment promises, "balance after the transfer" or dubious escrow schemes: stay away. Only cash at handover or a confirmed instant transfer — before keys and papers change hands — is safe.

Mistake 6: No written purchase contract

A handshake is not enough. The contract should record the vehicle data, mileage, known defects, price, warranty exclusion and handover terms. Only then are you released from responsibility after the handover — for the new keeper's fines or accidents, for example.

Mistake 7: Forgetting insurance and deregistration

After the sale, the transfer must be completed properly: cancel the registration document or report the change of keeper, return or reassign the number plates, inform your insurer. Reputable buying services handle these formalities for you.
