Keep in mind that at 4300 lbs the Bugatti is 1300 lbs heavier than the 3000 lb Enzo. That's a HUGE factor when it comes to handling. Also, the HP of the Bugatti is *only* 987, not 1200+. The horsepower gauge on the dash (seriously) only goes up to 1001. LOL.
Still an impressive car but given the extreme mass it may be a bit scary on a roadcourse. I was at the historics at Lagnua Seca when their test driver spun the 16.4 prototype off into the dirt at turn 3. LOL. The car is best suited for straight line and/or high banked oval blasts. Their goal was to create the fastest "production car"-- in a straight line. Also keep in mind the McLaren made 241mph and did so while being much, much more trackworthy at only 2500 lbs.
I'd still want one though, because it's an amazing design excersize.
The last silly-supercars I drove were an F-40 and an F-50. I'd have taken the F-40 over the F-50. I haven't had the opportunity to drive an Enzo and probably never well, but I would expect good things from it. I also bet it would be a blast to turn the "second key" on the Bugatti to turn the active aero features over to top speed configuration, find a long straight stretch, and hold the right pedal down for a good long time.
