This took a long time, and the cars cost a lot of money. Then a quicker and cheaper way of making cars was found. Instead of making all the parts at their own works, some car factories asked other factories to make some of them. All the parts were then fitted together in the car factories.

All the bits and pieces that make up each car are collected and put ready for the assembly line(裝配線) , where they are fitted together.
