Dear Motor-Talk municipality, I sold my used car privately. The buyer could visit the vehicle and turn a small round. I showed and described in detail all the existing optical and technical defects that I was aware of. This also included the hint that the vehicle has recently used cooling water. After long-distance travel > 300km had to be refilled. 5 days after picking up the vehicle, the buyer reported with the indication that the vehicle could be I then asked him to have the facts checked by a workshop. Now the buyer has reported again with the information that the workshop had confirmed the defect in the cylinder head seal. He demands the return of the vehicle and refers to a 14-day right of return, which is not known to me in the case of private vehicle sales. I have completed an ADAC sales contract for the private sale of a used car. Under 2. (damage in the time owned) we have set hooks under – no accident damage – no other damage (e.g. hail damage) Under 3. (damage in the other time) we did not make any entries, since other stains were already discussed in detail on site I know that I will not receive any legal advice here, but maybe there is a p aar hints, how I should behave now. Thank you in advance!
