The Mercedes-Benz W128 is a 6-cylinder luxury car produced by Mercedes-Benz from 1958 to 1960. It was available in sedan, coupé, or cabriolet body styles. Marketed as the Mercedes-Benz 220SE, it was the last of the "Ponton" series which had design roots and styling cues beginning in 1953 with the Mercedes-Benz 180 sedan (W120 chassis).
The 220SE featured a unitized body/frame construction and fully independent suspension. All models were fitted with Mercedes' M127 2.2 L (2195 cc) straight 6 gasoline engine with aluminum head, overhead camshaft, and Bosch mechanical fuel injection. An automatic clutch was available with the column-mounted 4-speed manual transmission.
At the time, the cabriolet was priced similar to Cadillac's Eldorado Biarritz (DM 23,400/$8,091). Nearly every interior surface of the coupé and cabriolet was covered in leather, and matching leather luggage was available. However, power steering, windows, air conditioning, and an automatic transmission were not available. The W128 was succeeded by the "Fintail" series starting with the W111 line.
The W128 sedan was produced from October 1958 to August 1959 and the Coupé and Cabriolet from July 1958 to November 1960.
The 220SE model designation lived on for a few more years with the 1959 220SEb "fin-body" sedans and the 1961 220SEb coupé and cabriolet (chassis W111).
