To me it it's "just a Viper". Yes they are very nice and fast BUT, I can still smoke my buddies in the 1/4 with my big block Nova. Go farther than that and he kills me. They also handle very nicely. What they DON'T do is drift well.
Wife and I were at Dover Raceway 3 years ago for the fall race and Chrysler had a bunch of cars and guys from the Richard Petty Driving Experiance doing ride alongs in an area of the parking lot, drifting with them. Worst drift car was the Viper, which I was in, best car was the Magnum wagon! which wife was in!
