If you want a luxury SUV with jaw-dropping off-road chops and an image of bravado that few vehicles outside a tank can match, then raise a salute and stand at attention for the Mercedes-Benz G-Class (aka the G-Wagen). The 2018 G550 is a brute, but it also boasts amenities expected in a 6-figure Mercedes-Benz. AMG models (reviewed separately) notch up the insanity with high-performance engines.
Reality check: Do you really need an SUV with triple-locking differentials, 13-mpg combined fuel economy and the ride quality of, well, a vehicle designed for the military? We get the appeal of driving such an exclusive, luxurious beast. But a Range Rover, Porsche Cayenne or any number of upscale SUVs will deliver far more comfort for far less money.
