Go for the Nissan Maxima, I have a 2002 maxima with a turbo, and a few other extras and get over 300 hp from it, on a 6 speed, very fast car. 2004 factory they are 265 hp, which u cant complain there, and did i mention it has plenty of stereo room, and tv, and even xbox room, so u can really pimp it out.
I think u can get a new se maxima for about 25,000 or even a little less, if you decided on a 2002 (about uner 20,000) then it comes with 255 hp
good luck, just a personal fav car of mine
