* When Ford first made the Model T it took a long time make one car. But later he planned to cut the manufacturing time of the car. For this he divided the works between the workers who will make each part separately. As his continuous effort, in 1913 he installed the first moving chassis assembly line to manufacture a car. When he started this process, between six months the production time of a Model T came down to almost 9 hours.

Although it was a bit above then the average salary of the Americans. However the car was still affordable and most of the Americans had it.Later the price was more reduced and Model T became one of the most popular cars in the America. From 1913 to 1927, Ford Company sold 15 million Model T cars.
