Hello! A car dealership has an interest in my used car and after a little e-mail pingpong sent a “purchase contract for used cars”. It contains all the data I have provided, a price and also the field for various things, in which the buyer has also noted the damages mentioned by me (kratzer etc.). This note is signed by him and he asks for my signature. Now for the damages which I have named him but also shown by photo. On my note that she is missing, he says, he can not remember everything, then it has after some back and forth. After I have signed it, then someone comes by, fetches the car and would also drive to the bank. The car dealership exists already, the buyer seems somewhat windy to me. Apart from my feeling of seriosity, what exactly do I sign there? I have a little blackmailed it up. What happens, for example, if he discovers in his manicure then I am obliged to give him a low price?
