2.5rs, outback/legacy, accord, gs-r sedan, 9-3/900 turbo, 9000 aero, 850 turbo. Thats all that pops into mind :dunno:
10k is a very annoying cutoff point because you can find some pretty nice cars for around 12k. I've seen WRX's under 10k, but they're usually kinda fishy.
I could include A4, except audi/vws suck
:edit: subaru SVX has the most weaksauce transmission on the planet, but I'm sure there are remedies for that. The one I drove was in dire need of nitrous.
