Let me re-phrase my answer since I missed a few key points. :bustin:
Lets pick high end Japanese, with a legendary bulletproof motor, low miles, not too old, and for $6k...
You're asking for a Supra for $6k. :nuts:
Luxury Japanese comes at a cost, motors like that are few and far between, low miles cost money, newer costs money. You have Supra tastes on a Honda budget, stick to your Honda or be prepared to give up a few requirements.
i have 4k now and should be getting at least 6k from the civic (selling because i want a less "targeted" car for thieves and problems keep coming up on this thing). if i could afford a clean gs400 i would not doubt get one but the automatic only is kind of a drag. a b13 is a possibility but its damn hard to find clean ones and the se-r only came in a coupe (not too big a deal but prefer a sedan).
i really want two cars, a nice luxury-ish sedan and a miata. but since two cars is not an option i need to combine the convenience and ergonomics of the sedan with the fun of the miata
edit: i forgot about my other choice, the impreza rs2.5 sedan. i doubt ill find one though
