Glasspar was a notable American manufacturer of fiberglass-bodied cars, operating during the mid-20th century. Founded by Bill Tritt in 1949, Glasspar gained recognition for its innovative use of fiberglass reinforced plastics (FRP) in automotive construction. The company produced a range of fiberglass body shells, kits, and complete cars, often used by enthusiasts and small manufacturers to create custom vehicles. One of Glasspar’s most famous creations was the Glasspar G2, a sleek sports car introduced in 1951, which featured a lightweight fiberglass body mounted on various chassis, including those from Ford and Volkswagen. While Glasspar ceased automobile production in the early 1960s, its legacy lives on in the continued popularity of fiberglass-bodied cars and its contribution to the development of alternative materials in automotive manufacturing.
