2.5 rs (assuming sedan 02-up)- recommended choice, not super quick, but has a little pickup compared to others and better on gas compared to WRX, and AWD makes it almost just as fun to drive.
WRX-Might be expensive for a sedan, but you can get a wagon for that price, it's just as good plus you get cargo space, oh wait, you're 16, never mind.
A4- sweet cars, but pretty unreliable if not maintained properly, expensive to maintain, not extremely fast, but can be made much faster somewhat easily
GTS- Yes unreliable, but then again its the only Eclipse i would ever buy
Ford-
For other options-Impreza's from 96-on are good and is what i think you should do. Wagon or sedan. No they're not quick but again they are fun cars to drive around with and i think that's just as good. Coupes 99-01 (i believe) are pretty sweet and really really good ones cost around 10 grand.
