When I stopped by Richmond BMW, they had a handful of X6s, including one that was near the customer lot with Style 215 21" wheels on it. It was a Space Gray 3.5i version with Black leather.
It's even more hideous in person than it is in pictures. The thing is ghastly, and I didn't mind saying so to the sales rep.
Edit: The pics are cell phone pics. So the quality isn't amazing.
