The Mercedes deal is called the "C Spot Drive Party." I don't have the link at the moment but I'll try to find it.
Just got back from the GM event. It was OK. I'm glad I went early, because later on it started to fill up, and the problem was you could never open the cars up because there was always someone in front of you obeying the 25MPH speed limit
. At that point, there wasn't really any reason to bother driving anything.
But the Z06 was cool - they gave me 3 laps. Stayed in 2nd for all 3... got up to about 6K RPM. That thing sticks like a mofo.... every time I thought I was going to get some understeer or oversteer it surprised me by just sticking, as if to say, "you didn't really think you'd hit my limit, did you?"
The H2 course was OK - the coolest part was a lateral incline that made the truck lean over about 45 degrees. Got a little scary.
Hopefully there will be more "fun" time on the Mercedes and Mazda courses...
