I found this Ford demo model in my late father-in-law's hobby stash. It's in pretty good shape and is in the original box. Anyone ever seen one of these and have any idea of what it would be worth to a collector? It's made of rather thick plastic and has a lot of descriptions written on the underside. I think it's a promo model handed out by dealerships as a premium to favored clients, etc. but can't say for sure as I've never seen one of these in the wild. Any help appreciated!
