If you're searching for a 2013 Mercedes-Benz SL-Class SL 550 Roadster for sale in Kent, Washington, your search ends here. North West Auto Empire, located in Kent in King County, has this stunning grand touring convertible in stock — a low-mileage, twin-turbocharged V8 roadster that represents one of the most iconic open-top driving experiences money can buy.

About This 2013 Mercedes-Benz SL 550 Roadster

The SL-Class is Mercedes-Benz at its most expressive — a two-seat roadster that blends racetrack heritage with genuine luxury. This particular 2013 SL 550 Roadster comes with impressively low mileage for its age, suggesting a well-cared-for vehicle that has lived a pampered life. The SL 550 sits above the entry-level SL 400 in the lineup, meaning buyers get the full V8 experience along with the elevated content and refinement that distinguishes this trim. Whether you're cruising Pacific Coast Highway or carving through the Cascade foothills, this roadster is built for exactly that kind of drive.

2013 Mercedes-Benz SL 550 Performance and Engine

Twin-Turbocharged V8 Power

At the heart of this SL 550 is Mercedes-Benz's legendary 4.6-liter twin-turbocharged V8 engine, producing around 429 horsepower and 516 lb-ft of torque. That torque figure is the real story here — it arrives early and stays flat across the RPM range, delivering confident passing power and effortless highway merging without ever needing to wring the engine out. The result is a car that feels both relaxed and deeply fast, depending entirely on your mood and your right foot.

Power is managed through the smooth-shifting 7-speed 7G-TRONIC automatic transmission, which in the SL 550 can be operated in fully automatic mode or nudged through the gears manually via steering-wheel-mounted paddles. The rear-wheel-drive layout keeps the driving experience pure and connected, rewarding drivers who enjoy genuine feedback from the road beneath them. Zero to 60 mph arrives in under 4.6 seconds, which — paired with the retractable hardtop — means this car is just as fast with the roof up as it is with it down.

Mercedes-Benz SL 550 Features and Interior

A Roadster That Refuses to Compromise on Comfort

The SL 550 Roadster is famous for its retractable hardtop, a folding metal roof that transforms the car from a sleek coupe to an open roadster in under 20 seconds. This isn't a canvas soft-top compromise — it's a fully insulated, weather-tight hardtop that means you can own this car as your everyday driver without worrying about the Pacific Northwest's famously grey skies.

Inside, expect a two-seat cockpit wrapped in premium materials, with features typically including COMAND navigation with touchpad control, a premium Burmester or HARMAN/KARDON sound system, heated and ventilated seats, dual-zone automatic climate control, and the iconic AIRSCARF neck-level heating system that blows warm air around the back of your neck — allowing top-down driving even on cooler Kent mornings. The SL 550 also includes AMG styling elements, larger alloy wheels, and sport-tuned suspension as standard equipment at this trim level.

Mercedes-Benz SL-Class Reliability and Ownership

What Owners and Experts Say About the R231 SL-Class

The 2013 SL 550 belongs to Mercedes-Benz's R231 generation, which was a significant overhaul over its predecessor — lighter, stiffer, and more technologically advanced. Owners consistently praise the twin-turbo V8's refinement and longevity when properly maintained, and the 7G-TRONIC transmission has an excellent reputation for smooth, reliable operation over many miles.

As with any European luxury vehicle, routine maintenance matters. The SL 550 rewards owners who follow the Mercedes-Benz service schedule — regular oil changes with the correct synthetic specification, attention to the hydraulic soft-top mechanism, and periodic inspection of the air suspension components where equipped. With only 53,695 miles showing, this example has significantly more life left than most, and the relatively low annual mileage suggests it was not used as a daily workhorse. Buyers with a pre-purchase inspection in mind will find this an excellent candidate.

Frequently Asked Questions

Is the 2013 Mercedes-Benz SL 550 a good buy?

Yes — the 2013 SL 550 is widely considered one of the best-value grand touring roadsters on the used market. It offers supercar-adjacent performance, genuine luxury, and a retractable hardtop that makes it a year-round usable vehicle. At 53,695 miles, this example is far from tired and represents exceptional value compared to buying new.

How many miles is too many on a used SL 550?

A well-maintained SL 550 with its 4.6-liter twin-turbo V8 and 7G-TRONIC transmission can realistically reach 150,000 miles or more. At just under 54,000 miles, this vehicle is firmly in the sweet spot — past the initial ownership period but with the majority of its usable life still ahead.

What does the SL 550 trim include over lesser SL models?

The SL 550 adds the twin-turbocharged 4.6-liter V8 (versus the V6 in the SL 400), upgraded braking hardware, AMG-styled exterior elements, larger wheels, and a more sport-focused suspension tune. It also typically includes a more premium audio system and additional driver assistance features as standard equipment.

Does the 2013 SL 550 have a retractable hardtop?

Yes. The SL-Class has featured a retractable electro-hydraulic hardtop — known as the Vario-Roof — for decades. It folds away in under 20 seconds, giving you the security and insulation of a coupe with the open-air experience of a roadster at the press of a button.

Is rear-wheel drive a concern for driving in the Pacific Northwest?

The SL 550 is primarily a fair-weather and year-round mild-climate vehicle, though modern traction control and stability management systems make it far more capable in wet conditions than RWD cars of previous generations. Most SL owners in the Pacific Northwest keep a set of quality all-season tires fitted for the rainy season and enjoy the car fully when conditions improve.
