I just spent 3 days driving around a road course in Nevada with a '06 Z06. Fantastic car!!! I have been a diehard Porsche fan since my early teens and have owned a new C2S from the past two generations. I will be selling my C2S and buying a '07 Z06.
Hate me yet?!
Other than the interior(Porsche hasn't created a great one either), the Corvette hit me hard with its Porsche beating accelaration and balance in corners after long slow braking.
Hate me more?!
I always firmly believed I was buying the best car for the money with the Porsches. I am a driver not a poser. The performance and "The Ring" numbers are irrifutable regardless of our Porsche affinity. On paper it's a better car and from my recent track experience the Z06 gets to from point A to Point B, in a straight line or around any number of curves, faster.
Sorry guys, but the overall picture favors the corvette.
