I just remembered that in 1968 I had a Renault Dauphine for a short while. Wife and I also had a couple of Mazda GLCs in the mid-late 80s, and the hatch, I'm sure, was smaller than the Rambler.The largest would be my 1988 and 1989 Ford F-350 4X4 Diesel trucks and the smallest would be the 1960 Rambler American 2-door station wagon.
Yes, just checked ... The Mazda hatch was about 10 inches shorter and about 11 inches narrow than the American. And the Renault was about 4 inches narrower and 4 inches shorter than the Mazda.
