Over the years, German presidents, chancellors and senior politicians have often used Mercedes-Benz S-Class vehicles and their predecessor models. The most famous variants were the Mercedes 300 series "Adenauer" and the stretched "Pullman" variants. Currently the State Car of the president of Germany is an armored Mercedes-Benz S600 with license plate "0–1", but the president has also used an Audi A8. The president is (besides the minister of defense) the only German official whose official car regularly shows a flag (a version of the President's standard) placed on the front of the hood.
