The Mercedes-Benz Type 300 were the company's largest and most-prestigious models throughout most of the
1950s. Analogous to the top of today's S-Class, the Type 300 cars were elegant, powerful, exclusive, and
expensive. Two body styles were available, a four door saloon and a four door cabriolet. The Type 300 Mercedes
Benz was equal in luxury and price but superior in performance to the rival Rolls-Royce Silver Cloud. These large
saloons and cabriolets incorporated many luxury features. Options such as Becker radio, VHF mobile telephone,
and dictation machine.
The four-door 300, 300b, 300c and successor 300d models were often referred to as Adenauers after Konrad
Adenauer, the first Chancellor of the Federal Republic of Germany. In office from 1949 to 1963, he employed six
custom convertible, hardtop, and landaulet versions during his tenure.
Introduced in August 1957, the 300d was the linear successor to the 300c, with a longer wheelbase, fuel
injection. Employing a slightly detuned version of the 300 SL sports car's Bosch fuel injected engine, the 300d
produced 180 PS (130 kW; 180 hp) at 5500 rpm. Automatic transmission was standard. Power brakes, power
steering, and Artic-Kar air-conditioning were added as options.
A total of 3,077 300d models were produced through March 1962, along with 65 special-order 300d-based
Cabriolet Ds priced at ($8432).
