Mercedes-Benz G-Class - 919 sales
If you've seen a Mercedes-Benz G-Class on the road, count yourself lucky -- with fewer than 1000 copies leaving dealerships last year, this is a rare beast indeed. And beast it is, as the Gelaendewagen is Benz's most hard-charging off-road machine. Originally developed for military use over four decades ago, the SUV is now hand-built in Austria. It's sold in two flavors, the G550 and G55 AMG. The former is propelled by a 382-horsepower, 5.5-liter V-8, while the AMG version uses a supercharger to augment that figure to 500 horsepower.
Even though it's decked out with enough leather and equipment to qualify as a luxury SUV, the G-Class suffers from poor name recognition in the U.S., coupled with a lofty price tag and dismal fuel mileage. The G550 starts at $106,625 and is rated at just 11 mpg city, 15 mpg highway. It's a niche vehicle: not many people need three locking differentials and leather seats and a wood steering wheel.
