Fox body mustang is cheap and fast, but it's not japanese. An old (like pre 1990)Supra, 300zx, or rx-7 would be pretty quick, but you'd have to worry about reliability because they are fast cars and they've probably been driven fast. Your best bet would either be a fox body mustang or an older DSM (eclipse, talon, plymouth laser) because they are such common cars, parts for them are a lot cheaper than other fast cars. An sr20 swapperd 240sx would be a good option too, but when something broke you might have to wait for parts to ship from japan.
