The Mercedes-Benz 600 or "Grand Mercedes" was a large luxury automobile, intended to represent the absolute pinnacle of automotive engineering. When introduced in 1963, it had few competitors, except Rolls-Royce and some stretched limousines. It was also, at that time, the most expensive car in the world. It replaced the
W189 as the top vehicle by Mercedez-Benz. The long wheel base version is called the 600 Pullman. Production eventually slowed down with the release of Mercedes-Benz's permanent flagship line, the
S-Class (W116), in 1972 but modest production continued until it was discontinued in 1981.
