Long-term ownership often tells the best story for a classic car like this 1973 Mercedes-Benz 450SL. Since 1991, the current owner has maintained this R107 with a clear focus on longevity and mechanical health. The car presents in the classic combination of Astral Silver Metallic over a black interior. While it shows 94k miles on the odometer, the extensive service records dating back to new provide a transparent history. This era of Mercedes engineering is famous for its vault-like build quality and effortless road manners. Finding an example that has stayed with one person for over three decades is increasingly rare in today’s market.
Exterior Presentation and Versatile Tops
The Astral Silver Metallic paint reflects the understated luxury typical of early seventies German design. It features both a black soft top for summer drives and a color-matched removable hardtop for colder months. Chrome-accented bumpers and side trim provide a bright contrast against the silver bodywork. Fog lights are mounted below the front bumper to assist with visibility. Although the soft top has a small repaired tear, the overall exterior remains cohesive and well-preserved. The car still carries its factory-correct 14-inch Bundt alloy wheels, which are a signature styling element of this chassis.
Extensive 2025 Mechanical Refresh
Preparation for the sale in 2025 involved a significant overhaul of the chassis and braking components. Technicians replaced the brake master cylinder, booster, calipers, pads, and rotors to ensure modern stopping reliability. Fresh tie rods and rear end links were installed to sharpen the steering response. New Hankook Kinergy ST tires were also mounted to the Bundt wheels during this service. These updates address the common wear points that often affect R107 models that have sat for periods. Consequently, the power steering and brake systems now benefit from completely fresh fluids and hardware.
Interior Appointments and Modern Tech
Inside, the cabin features highly durable Black MB-Tex upholstery on the bucket seats. This material is famous for resisting wear better than traditional leather over many decades. For modern convenience, the owner installed a Retro-style head unit that offers Bluetooth connectivity while maintaining a vintage look. Electric windows function as intended, providing easy ventilation. However, some classic quirks remain, such as a non-functional dashboard clock and air conditioning system. Despite these minor flaws, the VDO instrumentation remains clear and provides accurate readings for the driver.
V8 Engine Performance and Specs
The 4.5-liter V8 engine serves as the heart of the 1973 Mercedes-Benz 450SL, utilizing Bosch D-Jetronic fuel injection. This powerplant was factory rated at 190 horsepower and 240 lb-ft of torque. Recent maintenance in 2025 included a new fuel pump, fuel filter, fan clutch, and radiator hoses. Power reaches the rear wheels through a three-speed automatic transmission that recently received a fluid and filter change. The drive belts and battery were also replaced to ensure the car starts reliably. This engine is known for its smooth power delivery rather than aggressive acceleration.
Summary of the R107 Heritage
The 1973 Mercedes-Benz 450SL remains a benchmark for luxury roadsters because of its timeless design and robust drivetrain. This specific car offers a documented history that few other survivors can match. The recent 2025 mechanical work makes it a turn-key option for someone looking to enter R107 ownership. It represents a period when Mercedes-Benz prioritized over-engineering and long-term durability. While it has minor cosmetic and accessory needs, its core mechanical components are refreshed and ready for the road.
