This 1965 Spider looks to be in excellent condition, the seller claiming it to be rust-free and original with only 13k miles. The Spider was the world’s first production Wankel-powered car, and though this one’s factory single rotor turns freely it’s not currently running. Refurbishing an Ro80′s motor is difficult, and we imagine getting this one working again will be even more of a trial. Running examples do exist, however, and this one’s too special for a Mazda swap. Find it here on Craigslist in La Grange, Illinois for $19,500.
