Mercedes continued its tradition of quality in the mid-1950s with the 220S and 300 model range. The 220S was offered in saloon, coupe, and convertible form.
The 220S (W128) was produced in limited numbers from 1956 to 1959. It was the last of the "Ponton" series, which had begun in 1953 with the 180 and featured a unitized construction and fully independent suspension. It was powered by a 2.2-liter OHC, 6-cylinder engine with aluminum head. An automatic clutch was available, along with the column-mounted 4-speed manual transmission. The "Ponton" series was succeeded by the "Fintail" for 1960.
