I've been going out to Sears Pt. for years. Sometimes to drive the track, mostly to watch. The first time I drove on the track was with NASA (National Auto Sport Association) 12 years ago in a Mazda 323. The car was setup to oversteer for autocrossing so it was fun and I had a great instructor. The next time I drove a 1985 CRX si in a SCCA driving school. This car was also setup for autocrossing in CSP and it was fast. Fast enough that I had the quickest lap times that weekend against all other drivers including some who had Formula Fords!
I firmly believe that old cars are faster than new cars. I don't think I'd toss my Mini Cooper S through turn 10 at 100mph.
