When I was a kid, my folks had a Packard. I think gas was about 15 to 18 cents a gallon then.
But what I wanted to share is they would fill the space for feet in the back seat and then had some type of mattress they put over the whole thing and me and the two boxer dogs (our family pets, not the show dogs) had a BIG play pen for our trips, rofl. It was great!!!!!!
Love and hugs,
