I have been married 6 years, and my wife puts up with my car addiction (she has seen over a 100 cars come and go since we have been married) She never liked any of the Porsches (including the CayenneTT) and the only Ferrari she ever liked was the 04 575. I have learned that you do not need to share ever desire for a relationship to work. I'd suggest you enjoy your car whenever you can alone, since you are not going to enjoy it the way you try to drive it with her in the car. My wife drives an 07 Maserati Qport and she says that is loud.
