I bought a 1994 Ford Probe off craigslist for $100. It had been sitting for several years at an apartment complex and the owner was finally told to move it or lose it. I brought it home on the trailer, put a good battery in it and it fired right up and seems to run great. It has an exhaust leak and some condition issues but who could turn down a running car for $100? Haven't decided what to do with it yet, sell it, drive it, enduro car, rollover contest, who knows?
It's no RX-7... Nice project you have going on. Hope you're doing well.
