Dr. Herbert H. Hills, was the first owner of a production Buick. The story goes that he was not the first on a list of persons waiting for a new Buick. He was placed ahead of others because he agreed to let this vehicle be used as a demonstrator model. Some believe this car was built using the chassis and engine used on the Flint to Detroit test run. An article in the Flint Daily Journal July 29th stated the test car had been shipped to Chicago. We will probably never know for certain which is true. It is also believed to be the car that Billy Durant drove around Genesee county during the summer of 1904. Years later Walter Marr stated that the engine from the test Buick was seen by him being used to pump water in Chicago. This could help substantiate the story that the original test car was sent to Chicago. The large lamp was needed for night time driving.
