Don,
A few years ago one of the car magazines did a test of all of the top tuner cars, Calloway Corvette, Ford GT, ( the new GT-40 ), model, a couple of specialty Mustangs, and a Hennessey Viper. they bought a stock Corvette off a showroom floor to use as a base line for their tests. After all the testing was done, for all the extra money the so called tuner cars cost I would have gone for the stock corvette. Also they took them all down to Southern Calif. and ran them through a smog test. Two passed. The Ford Gt and the stock Corvette. If I had paid that much for a car that was advertised as 50 state legal, there would have been some serious problems when they failed the smog tests. and they failed badly.
