Mercedes-Benz Executive Sedan (W123)

The W123 is the Mercedes-Benz that owners still measure everything against — an executive saloon, estate, and coupé range whose build quality and durability became the firm's global reputation in the 1970s and 1980s.

From taxi-spec 200 D and 240 D diesels to fuel-injected 230 E and 280 E petrol models, the W123 covered every need with the same over-engineered chassis, independent suspension, and interior fit and finish that made deferred replacement a way of life. Estate S123 and coupé C123 variants extended the architecture without compromising the standard.

Between 1975 and 1985, 2,397,219 were built.
