From what my Chebbie friends tell me that Caddy is a ZR1 with caddy body panels and yeah they are really fast there is one up here in WI, I also have a friend that is the sales guy at the ford dealer here in GB and he gets to take out various models to our weekly car show, he has brought the new Sho's from time to time they are plenty fast too, the new Boss mustangs comming out are gonna be real Fast, and they are supposed to out handle the Gt500's, Dodge NEEDS to do something fast, the 6.4 hemi needs to get supercharged in a SRT8 chally from the factory. prolly not gonna happen... sadly, Hot rod or CC has an article on a street version of the Drag Pack Chally it was doing 12.00's still weighs 4100 pounds too. they had to add all that weight to make it street legal. what a joke,
