1958 BMW 503
BMW introduced the Type 503 at the IAA in 1955 as an elegant touring car and a more comfortable counterpart to the 507 Roadster. At almost DM 30,000, the car was even more expensive than the BMW 507 and was therefore only available to extremely wealthy buyers. As with the 507, the body design was developed by industrial designer Albrecht Graf Hertz.
Between December 1957 and May 1960, 193 examples of the second series Type 503 were built, of which 134 were built as coupes.
In addition, the car impresses with its elegant color combination and amazing performance for a car from the 50s.
