**EDIT** also your first year or two autocrossing whatever car you drive will not be competitive. Ask the stuck-up Ferrari driver who showed up to a Philly event how he did his first time I tried talking to the guy and he was just rude and stuck on himself saying stuff like "Ha! you drive a Honda."

I think it was my 3rd or 4th year autocrossing and I killed his time by about 10-15 seconds on that course. I thought that was fairly funny.

I remember my 1st year autocrossing and a stock Subaru Legacy GT station wagon (on R tires) KILLED me by about 15 seconds in my tricked out Civic. I was flabbergasted.

So any car you pick will be fine. I've seen everything from a Yugo to a Geo Metro and a Dodge Viper run. Your 1st year or 2 will be a learning experience. Get as much seat time as you can. And don't be afraid to ask for help - as most of us love helping out the new guys get acquianted with the sport. Don't even mod your car because it will just be wasted money. And a street setup will give better feedback than a racing setup and there are less variables you can blame on how you drive (good or bad).
