I have a friend who owns a 06 M5, and the black window trim is discoloring. It is like black paint oxidizes in that you can see the random disfigurization. He has attempted to clean, rub, wash, wax, etc etc the tirm areas, but to no effect. The problem disappears momentarily, but then returns. My advice was to return it to the dealer, but we both live some distance from the BMW store. In the interium, has anyone experienced this, or simular, and is there a cure? Thanks,
vz
