the prodrive P2 is pretty sweet.
Saleen = Definitely not. My buddy worked for Saleen and basically said that if he was given one he wouldn't drive it due to quality issues that he saw at work
Since you said "drive" I would have to go with the Bugatti EB110SS. Probably the coolest street car of all time in my opinion. The Bugatti Veyron is amazing as well, but I've been in love with the EB110 since I was like 10. In Silver please.
