The Dodge PowerWagon was introduced just after the end of World War II as an alternative to the military Ford 4x4 trucks, and was the first military style 4x4 to be sold directly to the public. A nicely restored PowerWagon is a cool piece of machinery, but power and suspension technology was primitive in the 1940s, so the driving experience won't be particularly noteworthy, unless someone drops the classic PowerWagon body on a modern chassis. Find this 1948 Dodge Powerwagon here on eBay bidding for $37,800 reserve-not-met with 4 days to go, located in Meridian, OH.
This is all the money and then some, for a classic pickup truck, even something as cool as the PowerWagon, but it is a good assumption that bidding is only a fraction of the amount the builder put into this beast. The seller says this thing cost at least $80k to build, so why not spend some of the other guy's money.
