Some people do not like the pearl white wrap I have on the roof of my E55, despite the fact that it almost exactly matches the pearl white leather inserts in the seating.
As a few of you may know, I don't like black, and the wrap does in fact, result is a lower cabin temperature in hot weather.
I cannot bring myself to doing the same thing with my W202, because there is no cue in the interior decor to justify a white roof wrap.
