I had a chance to hot lap a Z06 with the Z07 package at Streets of Willow. The performance that this car offers is mind boggling. It's performance is so far beyond 99% of the drivers that will ever own one.
One thing I love about the magnetic suspension is that the car is very predictable when pushing it in the corners, where as the older version would simply snap into oversteer with no warning.
I've got my eye on the Centennial Edition
