The 1955 Mercedes-Benz 300S Cabriolet A, chassis 188010-3500334, is one of only 203 examples of its body style built at Sindelfingen between 1952 and 1958. Delivered new to the United States in December 1954, this unrestored survivor retains its numbers-matching engine, original red leather interior, and factory Graphite Grey paintwork. Remaining with a single family from 1974 to 2021, it is considered an outstanding example of natural preservation among post-war European luxury automobiles.
