Id take the viper right to a chevy dealer and buy two vettes.... But in all seriousness, the new hennesy(SP) 1000tt is a beast. I dont know from experience though but ive read alot about how alot of little stuff on them break. I give both cars respect and wouldn't mind having either. But since ive owned two f-bodys (poor mans vette) i would have to lean towards the vette regardless of performance.
