I don't know if you folks down in the US, have track schools that teach the owners of Benzes how to "push" their machines to the limit.
Aside from taking you out on the track, they also take you to skid pads and offer F1 cars if you have the BLING $$$ to afford that part of the program.
The school is in Shannonville, Ontario which is between Ottawa and Toronto.
I just thought some of you folks might be interested.
BTW, I have never taken the school, but I have seen them in action numerous times, as I was partaking in a motorcycle school on the track beside the one they use (two tracks at the complex).
