Never before has a richly appointed lounge been able to accelerate or handle this well. Luxo-barge is probably the best way to describe the biggest Mercedes SUV, but this isn’t the 1970s Cadillac that such a name might evoke. Why? Because somehow Mercedes has managed to make this beast handle like a much smaller vehicle. No, it won’t handle like a GLC, but it’ll certainly shock anyone that thinks a big SUV has to handle poorly. Oh, and it’s wicked expensive.
