Aretired aeronautical engineer named Sterling ‘Smoke’ Gladwin, Jr., who had previously worked for Boeing and Lockheed envisioned a modern Sportster clothed with classic, pre-war-inspired coachwork. The body was formed from fiberglass and weighed just over 200 pounds. All but the first example rested on a modified Cadillac Eldorado frame with a wheelbase that measured 128 inches. The first car, Galdwin’s personal car, rested on a 1940 LaSalle chassis and was equipped with a Flathead Cadillac engine. Its design was similar to the cars that followed, but each car had unique features. A total of seven boattail speedsters were built along with an unknown number of body shells. Production continued through 1968 when Maverick Motors went out of business.
All but the first car was powered by a 331 cubic-inch overhead valve (OHV) Cadillac V8 engine.
