I know we've got links scattered about, but beyond the trucks in movies thread, I'm not aware of one that consolidates marketing or promotional films about our trucks.
We've got a vintage picture thread...and since there's no better resource IMO than images or video in period...I though we should have a vintage video thread. And there are a fair few videos by Chevrolet and even comparison videos by competitors that show the trucks in some detail available on the web.
So I'll kick it off with a good one. Here's 18 minutes of '72 Chevrolet promotional bliss. If you've only got a second, fast forward to the poor guy in the Bronco getting dragged backwards at 11:30...
