The Z06/Z07 are going to be astounding cars. For me, the most remarkable spec is GM's 5 year/100K powertrain warranty on a drivetrain with “at least” 625 HP and 635 ft-lbs of torque. M5s ate clutches for lunch with 40 percent less horsepower and torque. I can't believe I'm saying this, but I could be happy with an all-GM (all-Chevy!) 2-car garage: Chevy Volt for day-to-day use, and a Corvette Z06 for the fun car.
