Mercedes-Benz W120 model at a petrol station, 1961

The Mercedes-Benz W120 and W121 "Ponton" cars were produced from 1953 through 1962. They were sold under the "180" and "190" model names. The Ponton models were replaced by the W110 "Fintail" models beginning in 1961. The 180 was the first 'small' Mercedes, it can be thought as the C-class of that era. Mercedes-Benz would return to this market segment in 1982 with the 190E. The W121 190 was the E-class of the time. All the 'Ponton' generation models looked very similar in appearance, one could not clearly identify even a 220SE from a 180, only after seeing its larger size and chrome touches was it possible to identify it as a different model. This was the only generation in which all models looked incredibaly similar, though the 300 was exclusive.
A roadster variant, the R121, better known as the 190SL, was produced from 1955 to 1963.
Mercedes also produced 6-cylinder Ponton models, the larger W128/W180 220s.
