I don't particularly like powder coated OEM/stock wheels, but an aftermarket wheel of the appropriate design in black or graphite/gunmetal looks great on these cars. I do prefer wheels that are not completely black, like with a polished lip or the newer style wheels where there is basically a line around the diameter of the wheel (and sometimes the base of each wheel spoke) that is either silver or another color. I've seen some nice wheels on VWs that have a red accent around the diameter that I think would look pretty hot on a black crossfire. Hmmm, and I just happen to have a black crossfire.

Actually the black colored wheels on the upcoming Audi RS4 avant would be HOT on the crossfire, imo. See here: VWvortex Forums: Just Did Some New B8 Audi RS 4 CGIs Show Avant with New RS Wheel Design
