The Mercedes-Benz 300 SEL 6.3 was a full-sized luxury performance car built by Mercedes Benz from 1968 to 1972. It featured the company's powerful 6.3-liter M100 V8 from the flagship 600 (W100) limousine installed in the normally six-cylinder powered but top-end 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 the world's fastest four-door car.
A total of 6,526 300 SEL 6.3s were produced, and though quite costly to maintain are very collectible today.
