Who was talking abou drag racing? Yes, the GT is close - but it'll never be as fast. Even with a lot more hp the 400lb heavier GT won't make it around a track as fast as the Enzo.
I don't even like supercars that much! It's too risky for me - I'd rather work on my driving in a Miata or Elise than jump into one of them. Power is cool, but not worth it - at least not until I'm a mmuch better driver.
Anyway, the Enzo is the amazing. The GT is a MUCH better deal, but not as hard-core. It's not as fast. The C6 Z06 is an even better deal. So is the Ariel Atom, if you are looking for the ultimate in driving. BTW - I'd buy an Atom before an Enzo. The Atom is much faster in every way until you hit very high speeds, and it costs 1/10 the price. It's also just about as practical, and a better handler. But you wouldn't like it, 2Kewl4Skool: it's only 300hp.
