SewerMonster, it is indeed funny to see how gung-ho you are getting about this. "land of the free" and all that ignorant yuppie-talk. The question is not which is a better country, but which is a better car. As for your stupid claims of American Engineering and all its contributions to making this a free world, you might wanna take a look at the fact that over 60% of all Allied AirJet-Fighters were built by Ettore Bugatti, an Italian who settled in France. Mind you, his were the only jets that rivalled the Teutonic ones. But thats besides the point. The Point is, and excuse me for using such harsh terms, a viper is just another crappy american car with an engine the size of a refrigerator. If there is any American Car that is worth even mentioing in the supercar calibre, it is a Vette Z06. But even that is no match for a diablo. I tell you, it is ignorant, stubborn hicks like you, because of which america finds it so difficult to make a decent car.
