I read that some think that mud flaps are a no no. I just bought a 2009 CTS and want to avoid the stone damage that happened to my 2003 Jaguar. The body looks great except for paint chipped off right behind the front tires on both sides. There probably should have been some rubber-type molding on that area to prevent this. I don't want the same thing to happen to my new CTS. What do other owners do to prevent this? OR, maybe it's not a problem?
