Mercedes-Benz 300SEL 6.3 (Unknown)

Background

The Mercedes-Benz 300 SEL 6.3 is a full-sized luxury performance car built by Mercedes-Benz from 1967 to 1972. It featured the company's powerful 6.3-litre M100 V8 from the flagship 600 (W100) limousine installed in the normally six-cylinder powered Mercedes-Benz 300 SEL (W109). The result was a nearly 2-ton sports sedan with muscle car performance. At the time of its release it was one of the world's fastest four-door cars.
