The Mercedes-Benz W123, built from 1976 to 1986, is the mid-size Mercedes that became a legend for durability. About 2.7 million were built — a record for Mercedes at the time — and it became the default taxi across Germany, the Middle East and North Africa, with many covering hundreds of thousands of miles. It was the forerunner of the car later named E-Class, and diesel W123s are still in daily use in parts of the world today.

Why it was so tough

The W123 was over-engineered in the traditional Mercedes way: a strong body, simple mechanical fuel injection on many models, robust suspension and slow-revving diesel engines that were almost impossible to wear out. It was designed to be repaired rather than replaced, and parts were available everywhere.

The taxi of choice

German taxi drivers bought W123s in huge numbers — often in the regulation ivory color — because they ran and ran. After their taxi careers in Europe, many were exported to North Africa and the Middle East, where the W123 became the classic shared taxi. A car with an odometer showing several hundred thousand miles was common.

America’s diesel Mercedes

In the U.S., the 300 D and 240 D diesels built a loyal following in the late 1970s and early 1980s, especially during fuel shortages. The W123 also introduced Mercedes’ first factory station wagon (the S123), which became a favorite of American families.

Safety

The W123 brought S-Class safety to the mid-size class, including crumple zones, a safety steering column and, late in its life, ABS and a driver’s airbag as options — technology first introduced on the S-Class. See S-Class safety firsts.

Legacy

The W123’s reputation underpinned Mercedes’ image for decades: a Mercedes would outlast its owner. Many enthusiasts consider it the high point of Mercedes build quality. Its successor, the W124, was renamed E-Class in 1993.

That reputation for reliability is one reason professional drivers around the world trust Mercedes-Benz — from the W123 taxi to today’s S-Class and Sprinter. See our Mercedes-Benz S-Class and Mercedes-Benz Sprinter.
