I have a love-hate relationship with the G-Wagen, the 4×4 from Mercedes first introduced in 1972 as a military vehicle. I think that the contemporary, blinged-out AMG versions driven by celebrities and Hollywood moguls are an abomination, a crime against motoring humanity. But on the other hand, I’m quite partial to the older, more humble trucks on which they’re based. (I clearly have a thing for boxy old SUVs: I adore vintage Range Rovers, and used to own a Jeep Cherokee XJ, though the less said about that the better.) The original trucks are honest in a way the modern behemoths are not. The G-class was never supposed to be nice to drive, luxurious or a status symbol of wealth and conspicuous consumption. It was a spartan, utilitarian vehicle intended to transport soldiers across inhospitable terrain or, when sold to the public, farmers across boggy marshes.
