Buick Believing buyers of their farm wagons would be interested in buying many more Buick stationary engines Flint Wagon Works bought existing supplier
David Buick's business, Buick Motor Company, in September 1903 for its stationary and marine engines and its plans to manufacture automobile motors and transmissions. Flint Wagon Works built a suitable new building on the opposite side of West Kearsley Street. Some cars were built with these engines and sold with the brand name Whiting-Buick (after chairman James H Whiting). The first production Buick cars were built in that building in 1904.
Durant The Buick shareholders persuaded William C. Durant to take on its management. The capital was increased to $300,000 at the beginning of November 1904 when Durant took control. Begole replaced Whiting as president, Ballenger was secretary, Whiting remained a director and Durant joined them on the board of directors. In September 1905 a further $300,000 of capital was invested in cash and in addition more shares were issued to Durant in payment for $268,000 worth of patentable inventions and other property introduced by him. Durant moved manufacture to the former plant of
Imperial Wheel in Jackson, assembly remained in Flint where the bodies were made by Flint Wagon Works. Durant's friend,
Sam McLaughlin of Canada's
McLaughlin Motor Car Company, offshoot of another major carriage manufacturer, was one of the early customers for the engines because McLaughlin's own in-house design was not ready when their car production began. The manufacture of complete Buicks moved to Hamilton's Farm — Oak Park, Flint — but the engines did not follow until some years later. Buick engines continued to be made in the same building until 1908 or 1909.
Whiting automobiles Demand for Flint Wagon Works' horse-drawn vehicles maintained its steady decline in the face of the rapidly rising automobile trade. Flint Wagon Works let it be known in early 1909 they were developing new automobiles which would be available in 1910. Their Whiting model A and Whiting Model C were displayed at the
Detroit Auto Show in January 1910. The Model A was a light four-cylinder two-passenger roadster with an engine rated at 20 hp and the Model C was a five-passenger touring car with a four-cylinder motor rated at 40 hp. Both were of conventional design. Flint Wagon Works then fell deep into well-publicised and expensive litigation over their use of
Selden patent designs in their new engines. At first the Whiting cars were built in Detroit and Flint-made bodies were added to them then the whole production process was moved to Flint . Some 1200 Whiting cars were sold in 1910 but in the fall of 1910 Flint Wagon Works failed to make a loan repayment and their bank took control appointing a special board of directors. The bank's trusteeship ended in February 1911 when more than half a million dollars more capital was given to Flint Wagon Works which paid off the bank loan.
Durant Impressed by Durant's success the Flint Wagon Works directors invited Durant to invest in their own company on the condition that he participate in its management. By this time, 1911, Durant had organized
General Motors to hold not only Buick but Cadillac, Olds, Oakland and other successful automobile businesses. ==Terminal difficulties==
