Actually many vehicles are shipped in a similar multi-step fashion now. Most cars and trucks are produced in factories or delivered on ships to seaports then shipped via rail or truck to distribution points where all models a car manufacturer produces are kept on a lot and sorted for delivery to dealerships. I am sure you have seen trucks delivering these vehicles and have not even realized what was happening in front of you. If you notice most trucks delivering new cars and trucks to dealerships are not full of the same model but instead a mix of models, the multi-step distribution system is how this happens.
It's not so much the transportation part, it's the midpoint distribution centers I don't remember hearing about.
