How can you tell if a N* has been rebuilt? my mechanic said that mine was. I dont know if I bought a rebuilt engine. he said that if someone rebuilt an engine that if they didnt do it right it could lead to numerous problems in the future. But if they DID do it right I wont experience any problems at all. On the title of the car it said my 97 concours had 2 previous owners. I have had no problems so far with the car. I put approximately 4,000 miles on it since I bought it. But it leads me to believe that if the engine was rebuilt and had 2 previous owners and the interior and exterior is in MINT. Im wondering if I will experience the same?? Someone help me out here?
