Moin, I bought a Mercedes station wagon from private in November 2019 for 21500 euros. It was said during the sale that the bumper was repainted once ( I could have lived with it). Since I almost always drive by car alone, I do not open the rear doors very often. Today, however, it was so far. And there was a neat rusty crack to see. I then took a closer look at the whole thing and had to find out that not only the bumper, but both rear bumpers It’s all done relatively well, you have to say. But for me it’s certainly an accident car and I think I have to approach the seller somehow. In the purchase contract there is nothing about accident damage, so neither that it is accident-free, nor that there are pre-damages. ( What I find strange in hindsight in the case of a semi-professional contract of sale ) How do I best proceed? Must ic h prove to the seller that he had sold me an accident car? How can I prove that it is an accident car? Reviewer? Who then has to pay for the costs? What can be done to reduce the costs? Is it worth the effort? I actually have no interest in putting the car back and rewinding it, especially since then about 20000 km would count to me. However, I also don’t want to just leave it on me. Luckily, legal protection insured, but shy away from such disputes anyway. I would like to agree with the seller in a friendly way, but what can I ask of him? The seller did not buy the car new, so he is not the first owner, so he could say that he did not know about it. Car is Mercedes C-Class W205 250 diesel from 11/2014. Had at the time of sale 96500 km and sets 118000 has perhaps someone had similar experiences and can report about it, How did it end? Thank you very much.
