After owning a C6 Vette, my CS is definitely a more complete car, in my opinion. No disrespect for the Vette, they are also great cars and I never had a single problem with mine. The CS is just somehow that much better and more balanced.

That said, I have to admit the CS would be an absolute blast with a little more power. I'm not complaining, mind you. If the power difference really bothered me, I'd have kept the Vette.
