W124
E-Class
Overview
Widely regarded as the finest engineered sedan Mercedes-Benz ever produced, the W124 set the standard for build quality and durability in its era. Available as a sedan, coupe (C124), wagon (S124), and convertible (A124), it was the first to officially carry the E-Class name from 1993. The legendary 500E (built in partnership with Porsche) remains one of the most desirable sport sedans ever made.
