I attended MB "On Track" last year at Pocono Raceway. We got a few lessons from the pros on how to pick the correct entry point (for braking) when going into turns, choosing the apex of the corner (for getting back on the gas), and rolling on and off the throttle smoothly, so as not to upset the car when exiting the turn. Leaving the pits in a new SL55 AMG, and going full throttle all the way around the first turn was a blast. We got to run about twenty laps in all the AMG cars. We also ran a timed precision driving event in the new SLK's. It was basically an obstacle course. I gained a whole new appreciation for what these cars are capable of.
