There’s a great thread over on the Fordtruckenthusiasts website, in the 1942 to 1956 F-series discussion forum. It’s called “vintage pics of days gone by“ and has an amazing number of great old vintage photos.
Many of which show little tiny auto dealers like Todd was describing, with room for a one or two cars or trucks in the show room.
It’s a great read if you have a bout a month of spare time to start from the beginning!
