Mercedes-Benz has sold a number of automobiles with the “280” model name: W111, W113, W108, W114, W123 and W202. It is in production since 1959. The Mercedes-Benz W111 was a chassis code given to a range of Mercedes’ vehicles produced between 1959 and 1971, including 4-door sedans (1959-1968) and 2-door coupes and cabriolets (1961 to 1971). Introduced as inline 6-cylinder cars with 2.2-litre engines, the W111 spawned two lines of variants: entry-level vehicles sharing its chassis and bodies but 4-cylinder engines were designated the W110. A luxury version built on the W111 chassis with its body and the fuel-injected 3-litre M189 6-cylinder engine was designated the W112. A final model was added in August 1969, the 280 SE 3.5.
