I don't know if it applies at other dealers or not, but I just got back from mine and they said that they will replace bonnet/boot stripes one time at no charge. They know my car is less than 2 years old and still under warranty, and I wasn't there to ask a bunch of questions (since I was on my way to another place on an errand I thought I'd pop in and ask if they would do it, and when they said "yes", I made my appointment and got out). So I guess if your stripes are bad, its worth a shot asking what the dealer can/will do.
