My garage is home to both a C6 Z06 and a 2012 Camaro ZL1. Please remember that there is more than just base horsepower to compare. They are both animals. The ZL1 weighs in at 4120 lbs, about 1000 lbs more than my Z06. They are both track beasts. My Z06 is old, a 2006 and has many, many road track miles. The ZL1 no track miles, but I have driven a ZL1 on the road track and it is as advertised. Two very different cars for different people. I love them both. No gas guzzler tax on the Z06, a hefty gas guzzler tax on the ZL1. A more comfortable ride with mag suspension in the ZL1 and you can hold a conversation unlike my dear old Z06.
Just waiting a few days to see what the 2015 C7 Z06 will bring. Pretty sure that will join the ZL1 in my garage.
