Ah, you mean Stout scarab
Wikipedia:
The Stout Scarab is a 1930–1940s U.S automobile designed by William Bushnell Stout and manufactured by Stout Engineering Laboratories and later by Stout Motor Car Company of Detroit, Michigan.[1]
The Stout Scarab is credited by some as the world's first production minivan,[2] and a 1946 experimental prototype of the Scarab became the world's first car with a fiberglass bodyshell and air suspension.
