just one more question for now guys. my v i n starts with 138378....the code says the 38 after the 1 stands for concours, then the 37 means sport coupe. what does that actually mean? i've read that it means a special interior package or outside trim or whatever, but no one has satisfactorally explained this. how can you tell a concours from any other type? thanks for any input, it's very confusing.
