The Mercedes-Benz W123 Estate (T-Modell / S123) was introduced in 1977 as the practical wagon variant of the legendary W123 range, which itself launched in 1976. Built to Mercedes' famously exacting standards of durability and engineering, the estate featured a sophisticated rear suspension and generous cargo capacity. Powered by a range of four- and six-cylinder petrol and diesel engines — including the beloved 240D — the W123 Estate became synonymous with dependable, over-engineered German quality. Its robust construction meant many examples accumulated enormous mileages, and it developed a devoted following among those who valued longevity over fashion. Today, well-maintained examples are increasingly sought after by enthusiasts.
