A Mercedes-Benz Unimog U500. More than likely another one of the 184 US-spec Unimogs sold new in the United States during Mercedes-Benz' last effort to market the vehicle here from 2002-2007. Sales were handled through Freightliner dealers. Civilian-spec models were sold under the Mercedes-Benz name, while fleet vehicles bore the Freightliner nameplate. Park City owns two of these, and I think there might be another blue one down in the Provo area. So that makes four accounted for. Just another 180 to go.
