Good luck on your search but I'd suggest a base/limited 6spd Crossfire for you. I bought a SRT-4 when I was 18 with cash but I also left myself another 5-10k to play with after the purchase. With college coming up for you I would suggest having some free cash available since you won't want to be working two jobs while attending class. I sold my SRT-4 my Senior year because it became too expensive since all the things I wanted to do to it. Unlike the SRT-4 insurance and maintenance are not cheap on any trim Crossfire so make sure you take that into account. I got my SRT-6 at 22 and now am 24. Once again good luck on your search.
