The Opel Olympia is a compact car of the German car manufacturer Opel, which was then part of G.M. It was produced in 1935-1940, 1947-1953 and 1967-1970. It was one of the world’s first mass-produced cars with a unified body structure, following the Citroën Traction Avant of 1934.

The Opel Olympia received an updated body in January 1950, but the car was still based on the pre-war version. It was available as a 2-door sedan, convertible and station wagon. The car was powered by a 1.5-litre I4 engine mated to a 3-speed manual gearbox. In the roughly three years of production of this version, about 160 000 examples were sold.
