Purchased just one month before his untimely death, Tupac Shakur's Hummer H1 is up for bid through Boston-based RR Auction. The late rapper picked out and customized the vehicle himself, installing off-road lights, a 12,000 pound winch and 38-inch tires on Dick Cepek wheels. Inside the leather and wood-trimmed interior, there's a 12-disc Clarion sound system, complemented by an external PA system with three sirens. Under the hood is the standard 6.5-liter turbodiesel and automatic transmission, which was used to drive the Hummer all of 10,101 miles. Over the years it's changed hands through various owners, including Tupac's mother, then BET, who raffled away the Hummer in 2003, though the winner would end up selling it back to the Shakur estate. The H1 was auctioned again in 2010, and now the current owner has it back under the hammer, where it's expected to fetch over $100,000.
