Love shooting sand dunes, mud pits, and trails through the woods? The look into the Polaris RXR XP 1000 ($20,000+), one of the nuttiest dune buggies out there. Thanks to 29-inch Maxxis Bighorn tires, it has over a foot of ground clearance. Other fun features include 107 horsepower, 1000cc displacement, and is endlessly customizable. Windshields? Panels? Bumpers? Lighting? Ploughs? Storage? Winches? Pretty much whatever you want.
