I had an '08 Z06. I thought it would be the pinnacle of Corvettes, but I was wrong. Still, nothing wrong with a small block 427 with 505hp in a 3,200 lb car.
A friend of mine had two of them, which helped motivate me. He said his '06 was lighter and faster than his '07 and would break loose the tires as he accelerated though 85mph. It was yellow (the other one was Atomic Orange).
