Mazda Rev it up is nothing compared to Skip Barber's school. Mazda rev it up is very introductory while Skip's school is very advance. mazda cost $39 while skip's costs few hundred bucks for not even a day.
I think paying $150 to drive at a real race course while do a lot your your driving. Go to a loco race course if there is one in ur place. i live in LA, Cali so i plan to go to go to willow springs around June.
Once you have been at a race course, you'll see for yourself that money doesn't equal to speed. I seen guys with porsche's getting spanked by $20K cars like a miata. My friend spanked a
guy in a Integra GSR in the corners in his Camry Solara in the corners. On the way, he also spanked a couple of Eclipse GSR's.
