When shopping for my '02 M3 SMG Cab., I only looked at grey interior cars because that is what I wanted. A little over a month ago, a very sweet deal popped up for a car equipped the way I wanted but with BLACK interior. I couldn't pass it up and I figured I'd get used to it.
I'm used to it AND I'm glad I got the black interior. Believe me, it's hard enough keeping that clean.
