I have an 03 350Z and a 06 C6 (Z51, 3LT) and I have driven Modshack's 370Z. Both my cars are modded. The Vette is very fast and it's more comfortable than my 350Z on the highway, but it's not as much fun to drive. In my opinion the C6 lacks the overall feel of the 350Z and the 370Z. It feels bigger and heavier than it is because of its width and long wheelbase. The steering is also vague compared to the Zs and the shifter notchy. It's not as much of a driver's car as the Zs are.
If you want a nice 06 C6 mine is for sale with only 7,200 miles. It's got bolt ons and a tune as well as a custom leather interior. I purchased the Vette brand new in January of 2007. My next purchase is going to be a 370Z.
