From 1967 to 1973, the Mercedes 280SE could have referred to one of three vehicles. If it were a coupe or convertible, it was a 111 chassis. This was often called the "fintail", because of the design of the quarter panels. The 280SE sedans were built on the 108 platform. Both were full-size luxury cars, and were considered Mercedes flagship vehicles. In 1973, Mercedes introduced the 116 chassis which incorporated a new design style that would be applied across all future models. The new 280SE was the most underpowered of the entire line (up to 1980), but it sold the most units. Mercedes-Benz 280SE parts are becoming difficult to acquire; if you need to repair or replace your classic Mercedes flagship car, don't delay!
