I just picked up a '93 SSEi at an auction for $325. It has it'* problems including needing an engine swap. But the engine only cost me another $325. I'm doing all the work myself and will have it done in a couple days from now.
My suggestion is hit the auctions in your area and see what you can come up with. The body on my car is excellent. Having air ride, power moon roof, power seats, leather interior, heads up display, electric in dash compass, a premium sound system and all the rest of the options on the supercharged 3800 series one car is definitely worth the money that I will have into it when all is said and done. We're talking less than $1000.
