2015 Polaris Slingshot for Sale

This 2015 Slingshot packs a 2.4L GM Ecotec with a manual gearbox into three wheels and retro orange-black styling—basically a go-kart that got street legal and somehow stayed under $13k. If you want the visceral thrill of open-air driving without the motorcycle learning curve, this is the sleeper that proves Polaris nailed the brief.
