🔍 Model Background

The Mercedes 300 D Turbo (1982–1985) was the final evolution of the beloved W123 diesel sedans and remains one of the most iconic and durable Mercedes-Benz vehicles ever produced. As the turbocharged version of the 300 D, it combined legendary longevity with improved performance for North American drivers.

Under the hood was the 3.0-liter OM617.952 inline-five turbo-diesel engine, producing approximately 123 horsepower and 184 lb-ft of torque. This engine, paired with a 4-speed automatic transmission, offered dependable, low-maintenance operation and enhanced drivability compared to earlier non-turbo models.

The W123 platform was renowned for its bulletproof construction, comfortable ride, and precise German engineering. The 300 D Turbo featured independent suspension, power-assisted brakes, and excellent build quality, contributing to its reputation as a car that could easily surpass 500,000 miles with proper care.

Inside, the 300 D Turbo offered a simple yet elegant cabin, featuring durable MB-Tex or optional leather upholstery, wood trim, and climate control. While the features were modest by modern standards, the layout was ergonomic, and the materials were built to last.

Today, the Mercedes 300 D Turbo is a favorite among classic car enthusiasts, diesel fans, and collectors seeking a vintage car with unmatched reliability. Its timeless styling, efficient diesel powertrain, and solid engineering continue to make it a standout example of Mercedes-Benz’s golden era.
