The Mercedes-Benz W 108 and W 109 are luxury cars produced by Mercedes-Benz from 1965 through to 1972 to succeed the W 111 and W 112 "fintail" sedans. The cars were successful in West Germany and in export markets including North America and Southeast Asia. During the seven-year run, a total of 383,072 units were manufactured. Some publications mention 383,361 units.

Expert Note:
As a classic vehicle from the late 1960s, the Mercedes-Benz W109 SEL was not subjected to modern Euro NCAP safety tests. Its safety features are rudimentary by contemporary standards, focusing on robust construction rather than advanced occupant protection systems.
