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 Grosse Mercedes ("Grand Mercedes") succeeded the Type 300d "Adenauer" as the company's flagship model. It was positioned well above the 300-series Mercedes-Benz W112 in price, amenities, and status. Its few competitors included British and American equivalents from Rolls-Royce, Bentley, Lincoln, Cadillac, and Imperial. Generally, the short-wheelbase (SWB) models were designed to be owner-driven, whereas the long-wheelbase (LWB) and limousine models, often incorporating a central divider with power window, were intended for chauffeur operation
