Fraud when buying a used car.

Hello, I’m new here and I’m trying to be informative. I bought a used Renault mode from a used car dealer in Sept. 2009. In the purchase contract (ADAC) the seller writes to the point “damage” … Left fender in front renewed and means literally … The previous owner touched the garage wall. Since I noticed for a few weeks oddities on the car, I got to know about the previous owner/DEKRA etc. and learn that the car – 7 months before my purchase – had suffered a total damage and was not repaired in a repair shop. The question is, can I make some money in some form? The car had 16000 km at the purchase and today 36000 km. The black sheep do not die out. MfG fst70
