The factory Crossfire paint job is so good (no orange peel, excellent finish, durable paint) that a respray of similar quality is going to be hard to accomplish for reasonable money. IMO, it would be cheaper in the long run to trade your Crossfire for a black one of similar age and mileage.

Also, consider that black may look great when it is clean and waxed. Keeping it like that is a serious pain. I love my black coupe, but I don't think I will own another black car.
