The 2018 Mercedes-Benz SL450 remains a definitive choice for enthusiasts who demand a perfect balance of performance and long-distance comfort. This low-mileage example, showing only 8,000 miles, is finished in the sophisticated and rare Selenite Gray Magno matte paint. It represents the R231 generation at its peak, offering a twin-turbocharged powertrain that provides effortless acceleration on the highway. Having spent its life in California and Florida, the car presents in exceptional condition with a clean history. It features a power-retractable hardtop that transforms the vehicle from a quiet coupe into an open-air roadster in seconds. This SL450 is a versatile grand tourer designed for those who appreciate the finer details of German engineering and luxury. It serves as a modern classic that continues the storied legacy of the Sport Leicht nameplate.
Advanced Chassis and Active Body Control
The driving dynamics of this 2018 Mercedes-Benz SL450 are significantly enhanced by the Active Body Control (ABC) electronically adjustable suspension. This system actively counteracts body roll, pitch, and dive, ensuring the roadster remains flat through tight corners. It rides on upgraded 20-inch Vossen multi-spoke wheels that provide a more aggressive and custom aesthetic than the factory offerings. These wheels are mounted with Nitto tires that ensure the car maintains excellent grip in various weather conditions. Braking is handled by large, cross-drilled and ventilated rotors at all four corners for consistent stopping power. The combination of ABC technology and premium wheels results in a ride that is both supple and remarkably composed. Every input from the driver is met with a precise and refined response from the sophisticated chassis.
Designo White Leather and Cabin Innovation
Inside the cabin, the environment is defined by stunning Designo white leather upholstery that contrasts beautifully with the black leather dashboard. The multicontour power-adjustable seats are both heated and ventilated to provide year-round comfort for the driver and passenger. Airscarf neck-level heating ensures that top-down driving remains pleasant even when the external temperature begins to drop. A panoramic roof featuring Magic Sky Control allows the occupants to adjust the transparency of the glass with the touch of a button. For the audiophile, the Bang & Olufsen sound system delivers an immersive acoustic experience that remains clear at highway speeds. Modern driver aids like Distronic Plus adaptive cruise control and Lane Keep Assist make long journeys much safer and less taxing. It is a technological sanctuary that prioritizes the well-being of its occupants during every mile.
Performance Engineering and Maintenance History
Under the hood, the twin-turbocharged 3.0-liter V6 engine delivers power with a smooth and linear character that suits the car’s personality perfectly. To ensure the car remains in top mechanical shape, an oil change was recently performed in October 2025. The exterior benefits from a professional ceramic coating that protects the Magno matte finish from the elements and environmental contaminants. In February 2025, the trunk struts were replaced to ensure the power-retractable hardtop and cargo area continue to operate flawlessly. A replacement dashboard was also installed in June 2023, reflecting a high level of care for the interior’s longevity. These proactive service steps show that the current owner has prioritized reliability and cosmetic perfection since acquisition. This SL450 stands as a well-documented and mechanically sound example of Mercedes-Benz’s modern engineering prowess.
V6 Biturbo Specs and Transmission Details
The 3.0-liter M276 V6 engine produces a factory-rated 362 horsepower and a robust 369 lb-ft of torque for effortless cruising. This power is managed by the 9G-Tronic Plus nine-speed automatic transmission, which offers rapid shifts and excellent fuel efficiency at high speeds. The nine-speed unit ensures the engine stays within its optimal powerband during spirited driving while remaining nearly silent during coastal tours. Active LED headlights provide exceptional visibility during nighttime excursions, adapting their beam to the road and surrounding traffic. LED taillights and dual exhaust outlets complete the rear profile, giving the car a powerful and modern visual signature. Between the twin-turbocharged heart and the advanced transmission, the car offers a drivetrain that is as efficient as it is engaging. It is a setup that rewards the driver with smooth, relentless momentum on any road.
