Tin Lizzie, Ford Model T

The Model T was Ford's first automobile mass-produced on moving assembly lines with completely interchangeable parts, marketed to the middle class. Henry Ford said of the vehicle:
I will build a car for the great multitude. It will be large enough for the family, but small enough for the individual to run and care for. It will be constructed of the best materials, by the best men to be hired, after the simplest designs that modern engineering can devise. But it will be so low in price that no man making a good salary will be unable to own one – and enjoy with his family the blessing of hours of pleasure in God's great open spaces.
Although credit for the development of the assembly line belongs to Ransom E. Olds with the first mass-produced automobile, the Oldsmobile Curved Dash, beginning in 1901, the tremendous advancements in the efficiency of the system over the life of the Model T can be credited almost entirely to the vision of Ford and his engineers.
