🔍 Model Background

The Mercedes 380 SEL (1981–1983) was a long-wheelbase luxury sedan from the early W126 S-Class lineup, offering a blend of refined V8 performance, comfort, and advanced safety features. As one of the earliest W126 models, the 380 SEL reflected Mercedes-Benz’s commitment to innovation, quality, and understated executive style.

Under the hood was a 3.8-liter M116 SOHC V8 engine, producing approximately 155–160 horsepower and 196 lb-ft of torque in U.S.-spec form. Paired with a 4-speed automatic transmission, the engine emphasized smoothness and fuel efficiency over outright performance—particularly important during an era of stricter emissions and rising fuel concerns.

The long-wheelbase “SEL” variant offered increased rear legroom and improved ride quality, making it ideal for chauffeur-driven use or buyers seeking superior cabin space. The W126 chassis introduced lighter construction, improved aerodynamics, and advanced safety technologies like ABS (optional), crumple zones, and a driver airbag (introduced later in the series).

Inside, the 380 SEL was outfitted with leather or MB-Tex upholstery, burled walnut trim, automatic climate control, power windows and seats, and a quiet, well-insulated cabin. Its conservative yet elegant styling has aged gracefully, and today it’s appreciated as a durable, collectible luxury sedan from Mercedes-Benz’s overengineered era.
