Ah, but have you driven the most recent corvette? It's a totally different driving experience than a Porsche. That and while that interior might look good in magazines, it is NOT a nice place to be in in reality. Creaky and cheap are the first two words that come to mind.
My good friend has a C6, (not the Z06 though) and even after a year he still feels that the car is a bit intimidating to drive. You don't get the same sense of confidence that you get out of driving a Boxster--that sense that you can really wring the car out to its full potential. It requires a lot of faith to harness all that power for good.
We've done a number of canyon runs lately and I'm always either right on his butt or leaving him waaaaaaaaaay behind and he's no slouch of a driver.
