Re: cool vs reliable?
You've gotten a lot of good advice so far.
I agree with the above. Think of the acronym KISS, Keep It Simple ... Stick with American, I'd shoot for 90s personally, but understand that electronics can be a pain. Find something with 150-200HP and you should have a fun time. You won't be the fastest car, but you won't be the slowest. Your suspension will be OK, and the engine should be OK.
When we were looking for our first car I wanted something 'cool' and we ended up with an old Audi that's basically impossible to find parts for, and which has lasted all of 5 hours total out of two races. We'd probably have had a lot more fun if we had started with an Escort or a Malibu or something equally bland but mass produced.
Don't bother with a Miata or BMW because you'll get crap, and you're not going to win anyway, so don't pretend you are. Learn how to race with something that is within your driving abilities, and progress from there as you get older and more experienced.
