First GM vehicle in over 30 years and I am pleasantly surprised with the great quality , fit and finish - perfect paint and zero squeaks and rattles. Has been to dealer for a wheel balance but nothing else. Performance from the big V8 is wonderful - terrific low-end torque coupled with ferocious acceleration - gas mileage is 18-19mpg city and 26mpg highway. Brakes , handling , and shifter are quite nice - even better than a 911. Did not consider Porsche due to many past problems and very high service and maintenance expenses. Overall I am very pleased with my Z06.

Needs a fairly high-rpm (about 2,800) launch to overcome big-tire bog. Best run was with slight spin/bog/go. Shifter is slick, but gates could be more distinct. Linear power up to soft rev limiter. Third gear is still pretty short, so the car needed 4th for the quarter-mile. I didn't bother with the launch control function due to previous less-than-optimal results.
Medium/soft pedal with little idle stroke. Some dive, distances improved with repeated runs and heat up to fifth stop.
Skid pad: Decent info from steering wheel regarding front/rear grip levels. Neutral with a whiff of understeer at the limit. With ESP on, it chopped the throttle a bunch. Slalom: Crisp turn-in and very neutral (and non-threatening) behavior allowed me to steer it with the throttle at the rear. Late turn-in with that quick front-end bite worked best to pass by the "back" of each cone rather than going parallel to it.
