1964 Mercedes-Benz 600 4-door Pullman Limousine (W100)
Introduced in September 1963, it had very few competitors, these being Rolls-Royce, Bentley, Cadillac Fleetwood 75, the stretched Lehmann-Peterson Lincoln, and the Chrysler Imperial Crown Ghia. Generally, the long-wheel-base (LWB) 600 was intended as chauffeur-driven; many featured a central divider incorporating a powered window between front and rear compartments.
Short-wheel-base (SWB) 600 models were designed to be owner-driven.
