Now thats a toy! :) I love it even more it's on the ACR chassis. The Viper has always been a "good" car, and albeit my FAVORITE sports car, (i don't put it on the level of super car, or exotic) it has never been top of the line, or even worth it's price tag to me. The ACR model on the other hand I do put in the super car class, and worth it's price tag. They actually got that car right! Vipers though are great with after market parts, some of the best cars in the world if you got the cash for the multitude of TT upgrades. Fast as hell and you can keep it street legal.
So if that thing is built on the ACR chassis it's already got a + in my book. The HP is nice but can it put it on the ground successfully would be my next question.
I am still yet to do any research.
