Hello! Have an urgent question and indeed, a colleague of mine sold his car 6-8 weeks ago (because of unemployment), now came the buyer and says he wants to have the money again because allegedly an engine damage would be of which the seller did not know how to behave there!? Kaufvetrag was made the people also made test drive and the car ran without problems In the purchase contract is also bought as seen and so on. so in my opinion the buyer can not demand anything above all he has been on the road with it!? Or am I wrong informed? Please for quick help Thanks in front of the jet bitch
