CTS-V Coupe > Z28 any day. The Sigma chassis is leaps and bounds ahead of the Zeta chassis. Add Magnetic Ride Control and there is just no way for the Z28 to catch up. It is also much better looking inside and out.
I am glad to see that the 6060 is available. I heard that they were going strictly automatic. Glad to see that isn't the case.
Too bad there is no way I could afford one.
