Ford Model T

In 1908, the Ford Model T car, the first car model to be made on an assembly line, was introduced to the public at a price of $825. It was an immediate sensation. Before long, it was the largest selling car in the United States, often accounting for over half the sales in the country. True mass production was born with the Model T. As volumes rose, costs came down. By 1925, a coupe sold for $525 new, while a two-door runabout went for only $260. The first production Model T came off the assembly line on 27 Sep 1908, and the last Model T was celebrated on 26 May 1927.
