The BMW 503 is a two door 2+2 seater sports car unveiled by BMW at the 1955 Frankfurt Motor Show. Production got under way during the summer of the next year, and by 1959, when the 503 was withdrawn, 413 had been built, including 139 cabriolets.
The car was styled by the entrepreneurial auto-designer, Albrecht von Goertz, based on preliminary drafts prepared by Kurt Bredschneider.[citation needed] It was originally intended to feature a flamboyant shape incorporating rounded mudguards which would have emphasized its kinship with the BMW 502 sedan, but regulations concerning matters such as light positioning rendered such a form impractical. In retrospect, the more square cornered look of the car as it emerged with fully integrated wings may have been more in tune with future styling trends than the original proposal.
