Kevin's school used to be at Road Atlanta and they ran Suzuki's. I knew a few guys who did the school and were very pleased with it. Said there was a track walk with Kevin, lots of 1 on 1 instruction, and grouping never got more than 3 students to 1 instructor. There was plenty of track time as well as classroom time.
Personnaly though, I would rather use the money to buy track days and get track time with a good CR. You could get probably 12+ track days for the price of his three day school.
