Had a '98 black 540/6...with a fresh coat of Blitz it kicked butt. I never let anyone wash or wax my cars (not a single paint swirl on that car in 2 years), so the high maintenance killed me. The Florida sun also makes it pretty damned hot. My M5 is titanium/black exclusive...much easier to keep clean. I am selling my 2000--2001 on the way....what color now???!!!??? I have a little time to decide.
