The first time you see the Polaris Slingshot coming at you, it looks like a set piece from some big-budget Marvel movie. This is a mode of transportation for someone with a secret identity and superpowers. There's that wide arachnid front-end, skimming the pavement with spoilers and open-wheel fenders, a prototype racer from the future. The back end tapers to a point, where a hefty swing arm carries a carbon-fiber reinforced belt that drives a single tire. From the front seats forward, it's like a car, complete with bucket seats, a steering wheel, and a GM Ecotec engine hooked to a five-speed manual transmission. The owner of this unique ride was on a waiting list for nearly seven months, skip the wait and own this one today.
