i guess the real question is what do u wanna do with it? each car u mention has their own personality, traits and purpose..... if it was me, id go evo 5, simple as theres not much around an it stand out more from the import crowd over the wrx, but given the age, than its either the wrx or dc5r

bang for buck, neither cars are cheap to mod, lol, but for power to, $$$ turbo all the way

parts are plentiful for all models mentioned, just need the dough to mod em well
