The Mercedes-Benz 280C was a variant of the C123 Coupe that debuted for the 1978 model year. The 280 C was powered by Mercedes' M110 V 28 engine, which was a carbureted 2.8L inline six that generated 156hp. These cars were available with either a 4 speed manual or 4 speed automatic transmission, both of which sent drive to the rear wheels. Production of the 280C ended and the model series was replaced by the W123 Mercedes-Benz 280CE.
