The Skorpion, designed by Ralph Roberts and built By Jack Wills, were among the first fiberglass cars and used a somewhat-modified Crosley frame. Steve Cowdin owns two Skorpions and may be the world's foremost expert on the sports car, and interviewed John Wills in the '90s. The April 1952 Motor Trend told how Ralph Roberts started a 20-year career in 1921 at the LeBaron coachbuilders and then joined the Briggs corporation in Detroit, designing the 1941 Chrysler Thunderbolt and Packard Twelve and Chrysler Imperial customs. Jack Wills had worked in plastics since 1936, met Ralph, and created the Skorpion, America's first production fiberglass sports car through their Wilro Company, building about fifty Skorpion kits until early 1952, when they sold Wilro and the Skorpion to Doug Carruthers of Viking Craft, which built the Ford V8-60-powered Super Skorpion, then soon sold the Skorpion to Holloway Motors, which continued on briefly. John Wills' personal Skorpion still exists and appeared at the Petersen Automotive Museum recently, where the Skorpion was introduced in November, 1951 along with the Aerocar, Glasspar G2 and Lancer.
