Mercedes Unimog

We saved the weirdest for last. There are more varieties of the Mercedes Unimog – an industrial, agricultural, rescue, municipal, and/or military truck thing that has been in continuous production since just after World War II – than we can possibly list. Unimogs, with their flexible frames and giant tires, can drive over or through pretty much any obstacle smaller than a Motel 6. If this is your need, and you can find one that has been legally imported into the United States, then you should buy one.
