The original Hummer was the mainstay support vehicle for the U.S. military for decades, but it wasn't the most comfortable vehicle in civilian guise. Nor was it much of a performer outside of crawling over rocks, but Mil-Spec Automotive addresses all those shortcomings with its rebooted H1 project vehicles. Each one is custom-built per the customer's wishes, and that generally includes such niceties as massaging leather seats and modified suspension that enhances ride quality without compromising the H1's legendary off-road chops.

As for power, that's addressed too. This particular H1 gets a 6.6-litre Duramax diesel that's good for about 500 horsepower, and other projects are already in the pipeline. Costs can vary depending on the build, but expect to pay $250,000 (£190,000) or more for the ultimate civilian HumVee.
