W124 is the Mercedes-Benz internal chassis-designation for the 1984 to 1995/96 version of the Mercedes-Benz E-Class, as well as the first generation to be officially referred to as E-Class. The W124 models replaced the W123 models after 1984 and were succeeded by the W210 E-Class after 1995.
In North America, the W124 was sold for the 1985 through 1996 model years.
