There are quite a few cars that have exceeded those benchmarks by now. Many of them costing hundreds of thousands less.
Yes but those aren't in the same class. Not everyone wants the fastest car. Some people want cars for the look, style, and to say they have it.
And the only cars that cost less and are faster are the ZR-1, Viper ACR. Everything else is more expensive, Not street legal, or aren't really meant to be driven on the street.
