That's the easiest question ever, Viper. Although the GTR is an incredible machine, and the potential horsepower you have when buying one is insane, BUT it is a hideous car. The Viper, I think, may be one of the best looking american made cars ever. I think it is beautiful. Also, GTRs have become a common site, they are a lot of them out there. The viper is still a rarity to see, much less a 2013 one.
I have exhaust and an intake...
