yeah well remember the zr750 is tuned by hennessey so for roughly the same amount you can get a 1000hp dodge viper or for slightly more a 1200 hp viper I cant remember if it was road and track that did a test between this car the viper and the bugatti and few other supercars. When I find the magazine I will tell you the specs

Okay, I officially retract anything I ever said against this car.

GM before you die, send me one of these cars.
