Part 4-wheeler, part rail buggy, the new Polaris Ranger RZR 4 ($15,000) is the world's first four-seat sport side-by-side. Co-developed with racer Robby Gordon — or "Reckless Robby," as we like to call him — the RZR 4 boasts an 800cc High Output Twin EFI engine mounted behind the back seat for a lower center of gravity, a new suspension that includes Fox Podium X 2.0 Piggyback Reservoir Shocks and Chrome Moly front upper A-Arms, a rolled independent rear suspension, a true all-wheel-drive system, a 12-volt plug in and two cup holders for rear-seat passengers, cut-and-sew seats, and Maxxis Big Horn tires with Black Bruiser rims.
NASA's official night launches might be over, but you can recreate them with one of the remaining NASA Space Shuttles (roughly $28 million). Space Shuttle Discovery has already been sold, but Atlantis and Endeavour are both still available, representing not only a verified piece of human history but billions of dollars worth of government funded R&D. Plus, you know, it's actually been to space, not unlike a gigantic moon rock that you'll need more than just a little shelf space to display. [Thanks, Andrew]
