We did not have the chance to take this 550 over the hill and through the dell, but have off-roaded several 500s before and find them more capable than most of the people who buy them. You have so much to work with when negotiating tough terrain: superb approach and departure angles, full-time four-wheel drive, the three lockable diffs, high and low range, easy to modulate throttle, and manual gear selection. It's safe to say the G550 will take you any place you want to go, and a few places you probably shouldn't.
Any vehicle designed more than three decades ago is bound to suffer a few compromises. The front step-in height is high; the rear, even higher. We mentioned the wind noise. There are a few ergonomic foibles. Even Mercedes' latest nav system isn't as easy to use as some of the touch-screen models offered by others. And any time 382 horsepower meets 5500 pounds, fuel mileage will suffer (the EPA city/highway numbers are 11 and 15). Oh, and it costs $100 grand.
None of the above diminishes the G550's appeal. The current GL-Class was supposed to replace the G in the Mercedes-Benz lineup a few years back, but dealers and customers alike mounted a revolt. So, the company continues to import and sell them in limited numbers. If you're looking for a trendy, friendly, green crossover, shop elsewhere. The G550 is for discerning buyers who know quality, value things that are genuine, and can afford them. They want something different and couldn't care less about others' opinion of their choices. Although Mercedes has made no such statement, it's possible the new stricter CAF and emissions requirements may soon limit the G's lifespan in the North American marketplace. What a loss that would be.
