I just got back from the M5 driving experience. It was great and I met a lot of good people who were also car nuts. In between our track day they rolled out a blue Z8 with black/blue interior and a silver 2001 M3 with all black interior. The Z8 was more like automative art, it being obvious that style was very high on the list. The M3 was more business-like, with no particular design cues. I guess the fact that we had them surrounded by 10 M5's also came into play. These vehicles were there to train master technicians. They will be taken apart many times. We couldn't drive them, but the M3 had been previously driven hard by one of BMW's race-car drivers. Most of the professionals in attendance felt the M3 would be quickest around alsmost any track. Having seen these 2 great cars up close makes me realize that the M5 is certainly the best one for me. The other 2 have many merits, but I believe our cars have the best combination of speed, luxury and usefulness.
