Genuine Parts for the 300SL, SL320, SL500, SL600, and R129 AMG Models

The Mercedes-Benz W186 300, known around the world as the “Adenauer,” was not simply a luxury car. It was the car that announced Mercedes-Benz had returned to the top of the automotive world after the war. Introduced in 1951, the Type 300 became the brand’s flagship sedan and cabriolet, built for heads of state, business leaders, and owners who expected the best Stuttgart could offer.

Named after West German Chancellor Konrad Adenauer, who famously used several 300s as official cars, the W186 combined a 3.0-liter overhead-cam inline-six, a four-speed manual gearbox, central lubrication, and a level of hand-finished craftsmanship rarely seen in a production Mercedes-Benz. The series included the 300, 300b, and 300c, built from 1951 through 1957 before the related W189 300d arrived. Production was limited: Mercedes-Benz built 4,563 early 300 sedans, 1,639 300b sedans, and 1,367 300c sedans. Cabriolets were far rarer, with only 455 early examples, 136 300b Cabriolets, and 51 300c Cabriolet Ds produced.
