The Mercedes-Benz 600 (W100) is a line of ultra-luxury cars produced by Mercedes-Benz from 1963 to 1981. The forerunner of the modern Maybach marque, the 600 Grosser Mercedes ("Grand Mercedes") succeeded the Type 300d "Adenauer" as the company's flagship and most expensive model. It was positioned well above the 300-series Mercedes-Benz W112 in price, amenities, and status. Its few competitors included certain models of Rolls-Royce Silver Cloud III, Rolls-Royce Silver Shadow, Rolls-Royce Phantom V, Bentley S3 and Lincoln Continental Lehmann-Peterson. Generally, the short-wheelbase (SWB) models were designed to be owner-driven, whereas the long-wheelbase (LWB) and limousine (Pullman) models, often incorporating a central divider with power window, were intended for chauffeur operation.
