The Avanti was designed by an American, Raymond Loewy. He designed many of the classic Studebakers, many Streamliner trains, and the classic Coca-Cola bottle.
Until very recently, Jaguar sedan bodies and body parts were stamped out by Pressed Steel Fisher in the UK. Yup, same company (initially).
Fischer was originally a coachworks that designed and built their own bodies, but by the 80s, it was just a name for cars churned out by the GM design studios, and the bodywork was made at GM suppliers. GM bought the company in the early 60s. In 1964-65, they sold off the production facilities. PSF-UK was merged with BMC/British Leyland in 1965 and thus was taken out of the GM orbit.
General Motors bought 60 percent interest in Fisher Body in 1919 and the remaining 40 percent in 1926. Fisher built GM, Ford and Dodge bodies besides Studebakers. They also built airplanes during WWI and WWII.
