Try to imagine,if factories produce some components of the car,how will they deliver finished products?Consider the case of Ford with a factory in South Wales making fuel injection bodies that are going to be shipped to Spain to be fitted to engines.These engines may then be taken to Belgium to be put into the car body along with transmission parts from Germany.Finally the finished car may be delivered anywhere in the world for sale.So the long distance and heavy transport enable the sort of distributed manufactured goods that are common in the car industry.
