I'm surprised so many people are doubting this car. This is 1 car, it was SVSi's development car and I am even more surprised that so many people here haven't seen it before. In it's final evolution, the car was named the SVSi Stryker TTRS (Twin Turbo Rocket Sled). Some would argue that it would be one of the Viper worlds most important tuner cars ever built due to it's innovation and publication efforts. For over a decade this car continually set records in high hp, top speed, drag and the standing mile (Ergo: the evolution of the car and it's configuration / stance / body). Any of the old timers here on the board should be able to vouch for the car as well. Oh and from memory, the car dyno'd over 1700RWHP back in 2005 and more recently ran 8.40 in the 1/4 mile.
Now if the ad is legit, that's another story?
EDIT: Last time I saw the car, it had all the body mods (ebay ad pics with the SRT10 rims)
