I have a question for all of the experienced owners. I got my G35 coupe two weeks ago and know said anything to me about breaking the car in. I have been on the throttle quite hared several time and I have even tapped my rev limiter a few time. Am I toast my car has 840 miles on it now. I would say 65 percent of it is highway miles but I did get on it hard in the first couple hundred miles a few times. [^]
