Have gone to Bondurant and quite a few other schools, and frankly the best out there is the school at Miller Motorsports Park in Toelle, Utah. Cindi Lux is the lead instructor , is fantastic, and the Mustang GTs are great school cars. The track is absolutely the safest major track in the US , and yet quite technical , so one learns alot. Very easy going group out there, tons of track time, and though a Mustang is definitely not a Viper, it is torquey enough that the driving style will convert over to a Snake quite well.
Run Panoz, Berti-Roos, Bondurant, Bragg-Smith ( Corvettes ), Derek Daly, etc. ( some have been sold or changed management ) , and Miller is tops. Feel free to give me a ring if you have any questions, and I guarantee wherever you go, you will have fun and learn plenty.
