There's nothing quite like getting in your car at 120 degrees and playing hot potato with your seatbelt buckle before clicking it into place and bracing yourself for the slow and steady burn of the nylon belt. Let's face it: Cars are not made for the desert, but Local Motors is on a mission to change that. The hottest car on LM's Phoenix roster is the Rally Fighter, a car specifically designed to take on off-road desert terrain and catch the eyes of anyone cruising down I-10. But to get your hands on one, you'll have to help build it. Every car purchase comes with a commitment of either one week or two three-day stretches in which the buyer builds the car alongside one of Local Motor's mechanics — everything from laying brake lines to assembling the Chevy E-ROD LS3 engine. Yield: a uniquely badass (desert) experience.
