The small 1950 Mercedes-Benz 170 S Cabriolet A series of the 170S line-up was presented for the first time in May 1949 at the Hanover Technical Export Fair. Largely based on the W136 series, its development was rather quick and successful. The facilities and equipment weren’t damaged by Allied bombing on German soil during the war, which made its development easier. Because of this, Mercedes-Benz was able to quickly launch production of its mid-size cars after the war.
