During the war years, there were no cars produced for civilian use, according to my parents. Lots of rationing, tires & gas limited. I do know Ford was kept busy building Bombers, don't know about GM and Chrysler. For the most part, all of our industrial might turned to war production. My Dad had a Turkey Ranch, he & his brothers went to sign up after Pearl Harbor. The brothers were Army Air Corps. Dad was told to go back to his ranch & raise Turkeys for the Army.
So Marv, for us it would be Jeeps, Trucks, half tracks, etc...painted olive drab.
(edit) I love the lines of the '40 Ford Coupe. Never got around to having one though.
