spent the weekend at TX Motor Speedway driving expensive AMG iron at stupid speeds-great fun!! Drove SLS AMG,CL 63, SLK 55, E 63,CLS 63-amazing time. Look up AMG Academy on line too see whats offered-I recommend it w/o reservation if you have the time. I want to sign up for another course!!!The instructors were great as well, you never feel truly at risk, though they push you to do some wild things (skidpad!!!).
