I'm coming from the other direction. Sold my C6 last summer (it was my third) in anticipation of the C7. Got itchy for a another sports car so I went with a Z this time. Although I miss the sheer power of the Vette, I don't miss it's shortcomings and I find the Z a helluva lot more fun to drive. I've had ten Vettes and three Z's and I'm not sure what my next sports car might be. Usually I'd opt for the Vette, but the next gen NSX, GT-R and Z will be in the running, along with the C7 (unless they really screw it up).
Enjoy your Vette. It's an awesome car.
Below are a couple shots of my C6's and an interesting thread on the Corvette forum that addresses this very subject. Obviously, there are insecure tools on all forums.
