SO a few months back I purchased a 2011 370z and yesterday I had taken it to the shop to get the taillights tinted. Today when I went to pick it up the mechanic there asks me if I've ever been in an accident, I told him no why do you ask. He then proceeds to tell me that my rear quarter panel has previously been hit and if I didn't notice that the colors of the fenders and the rear bumper don't match up. I never noticed anything until he said something but now I'm feeling a certain way about this whole situation.. I'm paying top dollar for what I thought was a BRAND NEW car and I come to find out that I paid for something that's been in a previous accident! No! I just don't know what to do or where to even go to complain about this whole situation not to mention I've been driving the car for a few months now and I just hit 12k miles, and I'm at the point that even if I do go say something what can really be done? anybody have any similar issues or any suggestions on what I should do? any help would be very much appreciated.
