FYI: Henry Ford started his famous assembly line in 1913 for mass production of the Model T. It’s estimated that this idea decreased the time it took to build a car by close to 80%.
In order to keep the prices relatively low, Ford made every car the same so they could all be produced on the assembly line in an efficient manner. In fact, until 1925 the only color the car came in was black. There were no other choices like we have today in terms of custom features.
