First, the paint does not discolor (yellow). After two years, the clear film on the front bumper and other places has yellowed slightly to a point where it is noticeable in bright sunlight. It should be replaced after two years, in my opinion. A little discoloration is worth it to me because of all the highway stone chips I'd have without it. I have Cocoa leather and get many compliments on how rich it looks with white. I could not be happier with my choice of Carrara White. If you do get white, be prepared for a lot of admiring stares.
Good luck-Jay
