My great-uncle was the Hupmobil dealer in OKC during the 1920's and 1930's. His 2-story brick building is still in retail use, on automobile-ally in downtown OKC and close to the 'bricktown river-walk.' He was a successful businessman with an oil production & exploration company and the first 'modern' motor-hotel west of the Mississippi River. The Hupmobile car company and my uncle's dealership didn't make it past the great depression of 1929-39. His close friend and oil business partner, Fred Jones had the competing Ford dealership and a factory that re-built Ford engines & transmissions, (and was said to be close to Henry Ford). Oklahoma City, and much of the state was quite the hoppin' place (believe it or not) during the roaring 20's and oil booms at that time.
