About the Mercedes-Benz S-Class W126 Sedan

The Mercedes-Benz W126 S-Class Sedan arrived in 1980 as a technological tour de force, redefining the luxury sedan for a decade through two distinct series of production. Engineered with a focus on aerodynamics and safety—pioneering the use of airbags and traction control—the W126 was offered in both standard and long-wheelbase "SEL" forms, powered by a legendary range of inline-six and V8 engines. In the Australian market, the W126 is revered for its "hewn from granite" build quality, with the buyer pool primarily targeting the flagship 560SEL and the later 300SE for their perfect balance of prestige and durability. While thousands were built worldwide until 1991, genuine Australian-delivered examples with a documented local service history are increasingly high in desirability, especially those featuring the rare AMG performance kits or the ultimate 6.0-litre AMG conversions. Because these cars represented the pinnacle of global executive travel, they have solidified their status as blue-chip investments, with market value consistently climbing for well-preserved Series 2 models. Today, the W126 remains the definitive classic S-Class for local collectors who value a vehicle that still feels modern and composed on Australian roads.
