And almost all the parts used at Van Nuys had to travel 2500-3000 miles by rail to get there (other than gas tanks, seat foam, and carpets, which were sourced locally), and they maintained a huge "buffer" warehouse and rail receiving facility next door to protect material flow from occasional inbound transportation failures. The escalating costs of inbound freight were the prime reason for eventually closing the plant (along with all the other GM, Ford, and Chrysler California assembly plants).
