- Ransom Olds opened the first automobile factory in Detroit. During the first year of operations (1901), the company produced 425 cars. The 3-h.p., curved-dash Oldsmobile thus became the first real success among commercially sold U.S. automobiles. Ransom E. Olds became the first automobile manufacturer to gear up for genuine volume production. He introduced the curved-dash Olds priced at just $625 in an attempt to attract buyers. His plan worked for several years. Olds sold 425 the first year and 5,000 units by 1905, but as Henry Ford would ultimately discover with the Model T, mass production can set a dangerous trap. Changes in styling and consumer taste quickly stranded Olds with a huge investment in plant and equipment trying to sell the 'old-fashioned' curved-dash Olds.
