I can't explain the link you provided. Suspect some are scams as Mike suggested. A decent Factory Five Gen 1 or Gen 2 build is going to be $50 - 60K and up. A Gen 3 (a complete redesign with significant improvements) will be even more. Often hitting six figures. Especially if a high end build, well equipped, IRS, etc. There are deals to be had. But I'd be wary of listings less than these general ranges. There aren't nearly as many Coupes out there as Roadsters and generally they bring good money. I pay attention because I have one. We love it. Not for sale at any price.
