I vote for the saturn. With my current setup It went 10.75 in the eighth(don't laugh,LOL, I was running the HAI at 150f). Suspension is cheap for these cars, there already light(2300lbs with a/c, sunroof, and p/s), they don't dent, they come in a lot of flavors. I seriously want to autoX next year.

I would look for a crx or vx, great power to weight ratio there, in my opinion. Ufotofu just got a pretty sweet crx for 700 bucks, which is quite a deal, I think. Also saw a vx for sale for 1200 on NH CL. Good stuff there.
