Do you want: A fast car, something you can get sideways, or what?
So far people have suggested: Front drive, 1600cc wagons + 2 doors (toyota/honda things), Big 4WD fast whales (vr4 / legacy / wrx / GT4 ), big RWD whales ( soarer/skyline ), and lightweight turbo drift cars (silvia)...
From experience - I got my first turbo 4WD at 18, never had issues and never looked back since. I know plenty of 25 year olds who shouldn't have fast cars cause they're fckwits on the road, best option is just get thrown in the deep end in my opinion - experience counts for more than age, and there's only one way to get experienced!
Buy a stock car - be it a VR4, evo, silvia, skidline, whatever, just something DECENT - in stock form they are pretty tame, and probably as quick in a straight line as a modified 20V anyway so your not gonna get in too much trouble. Difference is, spend 2K on it and you'll get results you can actually feel and measure, as opposed to intake noise and 5hp at 8000rpm
