I would like to get some assembly plant discussion going. I have always pondered the amazing amounts of components that must go into the back doors of one of these plants. Although it's high on my list of things to do when I retire I have not had the opportunity to tour one. Parts like tires, wheels, windows, transmissions and on and on must come to these plants by the train load each day to fulfill the daily needs. Is there by chance anyone in here that can shed light on this challenging logistics nightmare?
