1971 Mercedes-Benz 600 SWB Pullman (W100). Serbian diplomatic car
The 600 replaced the Mercedes-Benz W189 limousine, which was nicknamed the Adenauer, after Konrad Adenauer, who employed several of these during his term as the first West German chancellor.
The 600 succeeded the 1961 Mercedes-Benz W112 in using a pneumatic self-levelling suspension, an enhancement of the Mercedes-Benz 300 Adenauer‘s dashboard activated mechanical torsion bar based system. A version is incorporated in Mercedes’ current Active Body Control.
