The Excalibur automobile was a car styled after the 1928 Mercedes-Benz SSK by Brooks Stevens for Studebaker. Stevens subsequently formed a company to manufacture and market the cars, which were conventional under their styling. A prototype premiered at car shows in 1964. Over 3,500 Excalibur cars were built. The company failed in 1986 but was revived several times. Production of the Excalibur continued until 1990.
