If you've been searching for a 2009 Mercedes-Benz SL-Class SL 550 Roadster for sale in Warren, MI, your search ends here. Empire Auto Collection has this iconic two-door convertible in stock right now — a low-mileage, rear-wheel-drive grand tourer that blends open-air luxury with genuine performance in a way very few cars on the road can match. With just 63,735 miles on the clock, this SL 550 represents an exceptional opportunity to own one of Stuttgart's finest at a fraction of its original sticker price.

About This 2009 Mercedes-Benz SL 550 Roadster

The SL-Class has always occupied a special place in the Mercedes-Benz lineup — it's not just a sports car, and it's not just a luxury cruiser. It's both, simultaneously, without compromise. The 2009 SL 550 sits at that sweet spot where the model was mature enough to have its early quirks ironed out but still benefitting from the R230 generation's classic, long-hood proportions and retractable hardtop design.

At 63,735 miles, this SL 550 is genuinely low mileage for a 2009 model year vehicle — averaging out to roughly 4,500 miles per year. That kind of usage pattern typically suggests a well-cared-for vehicle that spent its life as a weekend or seasonal driver, which is exactly how a car like this should be enjoyed. Buyers cross-shopping other SL 550s in the region will find it difficult to match this mileage at this price point.

2009 Mercedes-Benz SL 550 Performance and Engine

Under the long hood of this SL 550 lives a 5.5-liter V8 engine — one of the most satisfying naturally aspirated motors Mercedes-Benz ever produced. This engine delivers a broad, confident power band that makes effortless highway merging and spirited backroad drives equally enjoyable. It's not a stressed, highly-strung engine. It pulls smoothly from low rpm and builds to a genuinely exciting top end.

Paired to a 7-speed Touch Shift automatic transmission, gear changes are smooth and intuitive, with the added option of manual paddle control when you want to be more involved in the drive. Power is sent to the rear wheels — the way a true roadster should be configured — giving the SL 550 a balanced, rear-biased feel that front-wheel-drive luxury coupes simply cannot replicate.

Mercedes-Benz's ABC (Active Body Control) suspension system, standard on the SL 550, electronically manages body roll in real time, keeping the car flat through corners while still delivering a compliant, comfortable ride on Michigan's less-than-perfect roads. This is a car that drives as good as it looks.

Mercedes-Benz SL 550 Features and Interior

The SL 550 trim places this vehicle firmly in luxury roadster territory. The retractable hardtop — one of the engineering marvels of its era — folds away in just 16 seconds, transforming the car from a sleek coupe to an open-air convertible without the compromises of a fabric soft top. You get the security and refinement of a hardtop with the freedom of a convertible.

Inside, the cabin is driver-focused and richly appointed. Expect premium leather seating, genuine wood and aluminum trim elements, dual-zone automatic climate control, and Mercedes-Benz's COMAND infotainment interface. The SL 550 also features Airscarf — Mercedes-Benz's neck-level heating system built into the headrests — which extends open-top driving well into Michigan's cooler fall months.

Additional features typical of this trim and generation include a Bose premium audio system, power-adjustable heated front seats, rain-sensing wipers, automatic headlights, and Mercedes-Benz's Attention Assist and Pre-Safe systems. This is a car packed with technology that was genuinely ahead of its time in 2009 and remains impressive today.

Mercedes-Benz SL 550 Reliability and Ownership

The R230-generation SL-Class — which includes this 2009 model — earned a reputation as one of the more reliable Mercedes-Benz grand tourers of the era when properly maintained. The 5.5-liter V8 is a robust, proven engine that can comfortably run well past 150,000 miles with regular oil changes and attentive service.

Prospective buyers should be aware that the ABC suspension system, while brilliant, does require periodic maintenance. At this mileage, checking the condition of the hydraulic fluid and the accumulator spheres is a standard due-diligence item — something any independent Mercedes-Benz specialist can assess quickly. The retractable hardtop mechanism is similarly long-lived when serviced regularly.

Owner feedback on the 2009 SL 550 consistently highlights the engine's longevity, the stunning driving experience, and the way the car holds its visual appeal over time. With low mileage like this example carries, many of the high-wear components are still in excellent shape. This is a car you buy to enjoy for years, not just weeks.

Frequently Asked Questions

Is the 2009 Mercedes-Benz SL 550 a good buy?

Yes — for the right buyer, the 2009 SL 550 represents outstanding value. New, these cars sold for well over $100,000. At current pre-owned pricing, you're accessing a genuine grand touring roadster with a powerful V8, retractable hardtop, and luxury features at a fraction of that cost. Low-mileage examples like this one are particularly strong buys.
 

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

A well-maintained SL 550 can run reliably to 150,000 miles and beyond. At 63,735 miles, this example is well within the sweet spot — old enough to have depreciated significantly from its original price, but young enough in terms of wear that major drivetrain components still have substantial life remaining.
 

What does the SL 550 trim include over the base SL?

The SL 550 steps up from the SL 550 with the larger 5.5-liter V8 engine versus the base 3.5-liter V6, delivering meaningfully more power and a more immersive driving experience. The SL 550 also typically includes a more complete feature set including the Active Body Control suspension, Airscarf neck heating, and upgraded audio and interior trim.
 

Is the retractable hardtop on the SL-Class reliable?

Mercedes-Benz's Vario-Roof retractable hardtop is a well-engineered system that has proven durable over time. Routine maintenance — primarily keeping the hydraulic system in good condition and the roof seals clean — goes a long way. On a low-mileage example like this, the roof mechanism typically operates exactly as it should.
 

What should I check before buying a used SL 550?

Key inspection points include the ABC suspension system (hydraulic fluid and accumulators), roof operation and seals, any signs of rust or water intrusion in the trunk area, transmission fluid condition, and service history. A pre-purchase inspection from a Mercedes-Benz specialist is always a smart step on any used SL-Class purchase.
