Atlanta is a scary place to turn the kids loose on the roads. After attending two Street Survival courses with my teenagers, I'd recommend cars that handle VERY well with just enough power to get out of the way. I watched car after car after car after car that could not do the avoidance manuevers because they were undersprung wallowing pigs. Even smaller cars were terrible.
One son has an Mazda MP3 (I ended up winning G-stock with that one on a Sunday) and my other son has a ZX2 - I ripped the sloshy suspension out of it and put in the S/R suspension so it would handle way better. Both of these cars did quite well in the avoidance manuevers and subsequent autocross. Good brakes, good handling, nimble, and two airbags. And go ahead and pay the money for excellent tires!
