It was a black C6, didn't run like it was a Z06. I got there about 1:10 and had no sooner sat down on the bleachers with my two daughters that it happened. Wiggled a little bit on the transition, possibly gear change, then it just went left like he steered the car into a skid. It slid the nose down the wall, then he romped the throttle spun it off the barrier and damn near into the other wall. Once it completely stopped, he turned around and drove down the track and up the return lane on its own power.
