Unimogs show up regularly for sale up here in BC. They tend to be used in the logging industry by private operators and are generally "well used" when they come up for sale.

They are seriously heavy duty machines but the older 1970s and 1960s models that come up for sale are best suited to REAL off-road use in tough country. Top road speed and operator comfort are low and fuel consumption is high. If you are used to a North American half ton 4X4 you'll get a shock driving one of these on an asphalt road.

There are several on the Vancouver Craigs List right now.
