Personally I reckon you'd be doing well to find a manual 95 or newer under $18,500 that was worth paying money for.
even if you import them through a broker you wont do much better than that. just remember - there's about a three thousand dollar premium on the manual box.
so for a 93 - you might find one for $17 ?
btw - I had a listen to Rev210s car the other night, and it sounded pretty healthy. that flywheel makes it so much more free-revving!
