If you are not too concerned about gas, I'm sure you could find a 4th gen LS1 Camaro or Firebird for that. Cobalt SS or Neon SRT4 if you are into FWD turbos, though I'd question the Neon's reliablity, and you would proabably be hard pressed to find a turbo Cobalt SS on a $10K budget.

I'll get flamed for this by someone, but you can probably do a lot with a Miata for $10k. I know that probably violates your "girl car" criteria, but they are actually serious sports cars, high handling limits, RWD, get great gas mileage, reliable, and have a big aftermarket available. You could probably find a good 350Z, also a RWD sports car, but with more punch, and more muscular styling.

Whatever you get, though, make sure to shop for insurance quotes before making a decision. At your age, certain cars can really be expensive to insure.
