Hello! I sold my car in December (Audi 80 Bj.91) and now the buyer suddenly reports after more than three months with a problem. The buyer writes me that the car has a motor damage and he was forced to install a used engine. The cost is about 1200 €. He wants to have refunded at least half of the costs because the engine was supposed to have been planned before. But I know nothing about that, since I am 2nd hand and bought the car only in 2000. I am not informed about the history of the vehicle. I was served by the Audi for 4 years without great problems. Now that he has it he is dissatisfied. It may also be that he did not run the car properly. As a private salesman he cannot demand a guarantee from me! Now the buyer wants to go to court with me or he wrote me that he wants to sue me. What does it look like for me? I am not aware of any fault. Have my Audi for 1500€ ve rkauft and so seen I would sell it for 900€ if I would pay him half the bill. I used a purchase contract of course (ADAC). Thank you for your answers Gruss CARMAN
