Ford Model T: Over 15 Million
There are not enough words to describe the importance of the Ford Model T in automotive history and the car culture. This was the car that singlehandedly created the car world in 1908. The Model T was the first truly mass-produced automobile with Ford building over 15 million of them until 1927.
Also, it was a car that motorized the world, creating the foundation for the modern car industry with assembly plants in foreign countries and on other continents. When they presented the Model T in 1908, the world was still using horse-drawn carriages. But by the time Ford discontinued it in 1927, the automobile age had successfully started.
