At first glance I thought: oh, a nice load of mixed cars from the post AMC merger with Chrysler. But no, there weren’t any Alliances sold by then. And the picture is dated September 1984, so this is a coincidence, of sorts.
Once again we see a Convoy oversized rig as used in the Northwest. They mainly picked up cars shipped up to the ports and then distributed them regionally to dealers. I assume that’s what this load is too.
