Keith from CorvetteBlogger reminded me that he had blogged about Mario Andretti's process of replacing his Z06 with a ZR1. According to Keith, Mario is hoping to be the owner of car #500!
Another ZR1 buyer is Paul Teutul, Sr. of Orange County Choppers. I hope he doesn't convert it into a cycle! That would be some Corvette Convertible, wouldn't it? Paul looks like he will enjoy the ZR1 just like it is, though, right? See Paul's 2006 Z06 here, and his ZR1 past the jump.
Who are the other 350 or so who have bought them?
