This 2015 Mercedes-Benz S550 represents the modern peak of Mercedes-Benz full-size luxury sedans, combining twin-turbocharged V8 performance, advanced driver assistance systems, and long-distance comfort in a highly engineered package. Purchased new by the seller from Star Motor Cars of Houston, this example is finished in Anthracite Blue Metallic over Silk Beige and Espresso Brown leather and shows 89k miles under single ownership.

Power comes from a twin-turbocharged 4.7-liter V8 rated at 449 horsepower and 516 lb-ft of torque. Paired with a 7G-Tronic seven-speed automatic transmission and 4MATIC all-wheel drive, it delivers effortless acceleration with strong midrange response and confident traction in all conditions. Airmatic air suspension further enhances ride quality, automatically adapting to road conditions for a composed, isolated driving experience.

The exterior reflects the understated elegance of the W222 generation, featuring LED headlights, Parktronic parking sensors, soft-close doors, and a panoramic sunroof. It rides on 19″ split-spoke alloy wheels wrapped in Continental tires. Service history notes recent tire replacement and brake system work in 2024–2025, including pads, rotors, a caliper, brake lines, and fluid service, along with additional suspension and drivetrain maintenance. Some cosmetic wear is present, including curb rash on wheels, paint chips on the front end, and rear bumper damage from a 2026 incident listed on the Carfax report.

Inside, the cabin showcases Mercedes-Benz’s focus on modern luxury, with Silk Beige leather upholstery covering the seats, dashboard, and door panels. The front seats are heated, ventilated, and feature massage functionality. Additional amenities include ambient lighting, rear and rear-side sunshades, Keyless-Go, a Burmester surround sound system, dual-zone automatic climate control, and COMAND infotainment with navigation. Driver assistance systems are extensive, including Active Blind Spot Assist, Active Brake Assist, Active Park Assist, and Distronic adaptive cruise control.

The driver is presented with a leather-wrapped steering wheel framing a fully digital 12.3-inch instrument cluster, displaying a 160-mph speedometer and a tachometer with a 6,250-rpm redline. The digital odometer shows 89k miles, all accumulated under current ownership.

Recent mechanical work includes resealing of the upper timing cover, replacement of ignition components, intake hoses, batteries, and a full “B” service, supporting continued reliability in a complex modern platform.

Blending V8 performance with high-end comfort and advanced safety technology, this S550 stands as a well-equipped example of Mercedes-Benz’s flagship sedan philosophy—best suited as a long-distance luxury cruiser with serious performance capability when called upon.
