• Mercedes-Benz 300 W 186 and W 189 (1951 - 1962).

The Mercedes-Benz 300 (W 186) is today known primarily by its nickname, the “Adenauer Mercedes”.

Konrad Adenauer, the first chancellor of the Federal Republic of Germany, was among the first users of this new flagship Mercedes-Benz model of 1951 and was henceforth only ever to be seen being chauffeured around in a Mercedes-Benz 300. On being launched at the first IAA International Motor Show in Frankfurt in April 1951, six years after the end of World War II, the Mercedes-Benz 300 heralded, like scarcely any other vehicle, Germany’s return to the international automotive market.
