The Mercedes-Benz 600 (W100) is a line of ultra-luxury cars produced by Daimler-Benz from 1963 to 1981. The forerunner of the modern Maybach marque, the Grosser Mercedes succeeded the Type 300d "Adenauer" as the company's flagship model. It was positioned above the 300-series Mercedes-Benz W112 in price, amenities, and status. Its few competitors included British and American equivalents such as Rolls-Royce, Bentley, Lincoln Continental, Cadillac Series 75, and Imperial. It was well known for its ownership among celebrities and political leaders throughout the late 20th century.

The Mercedes-Benz W189 model 300 was a four-door luxury tourer produced by Mercedes-Benz between 1957 and 1962. It was the company's flagship model at the time, equivalent to the modern S-Class and Maybach.
