2018 MERCEDES-BENZ GLS GLS 550 4MATIC SPORT UTILITY 4D

Up for your consideration is this 2018 Mercedes-Benz GLS 550 4MATIC, a full-size luxury SUV that delivers **serious V8 performance, world-class comfort, premium craftsmanship, and true 3-row family versatility**. Powered by Mercedes-Benz’s impressive **4.7L bi-turbo V8 engine** paired with a smooth **9-speed automatic transmission** and legendary **4MATIC all-wheel drive**, this GLS 550 offers an incredible balance of luxury and power that few SUVs can match. With over **440 horsepower**, this SUV moves with authority while still maintaining the refined ride Mercedes is famous for.

This is the flagship SUV experience buyers look for when they want something beyond the ordinary. The GLS 550 combines the road presence of a luxury SUV with the performance of a sports sedan. Whether you’re hauling family, towing, road-tripping, or simply commuting in comfort, this Mercedes delivers a first-class driving experience every time.

One of the biggest highlights on this GLS is the **extensive maintenance history**. CARFAX shows an impressive **24 documented service records**, with servicing performed consistently at highly respected shops including **Mercedes-Benz of Bellevue, Mercedes-Benz of Tacoma, Integrity Automotive, Big O Tires, and Rolf’s Import Auto Service**. This is exactly the kind of maintenance history we love seeing on high-end German luxury vehicles because it reflects consistent preventative care rather than deferred maintenance.

The service history is especially strong with multiple major maintenance items already completed, including **water pump replacement, engine mount replacement, left axle replacement, serpentine belt replacement, thermostat replacement, brake pads and rotors front and rear, multiple tire replacements, wheel repair, coolant flushes, A/C service, radiator hose replacement, exhaust manifold bolt and gasket replacement, alignment services, and regular oil changes**. A huge recent service in **February 2026** included **A/C refrigerant recharge, A/C system flush, coolant service, exhaust repairs, alignment, and fresh oil service**. That kind of recent maintenance adds meaningful peace of mind for the next owner.

CARFAX shows this GLS spent its entire life right here in **Washington State**, which is a nice bonus for local buyers. The first owner kept it for nearly **6 years**, averaging just over **13,000 miles per year**, which is below industry average and another strong indicator of consistent ownership.

CARFAX does report **one minor damage incident** in **September 2021**. Importantly, it is classified as **minor damage**, which generally means cosmetic-type damage such as scratches, scuffs, or small dents. Just as important, there is **no salvage history, no rebuilt title history, no structural damage reported, and no airbag deployment reported**.

The GLS 550 continues to be one of the most desirable luxury SUVs because it offers something special — **true 7-passenger luxury, bi-turbo V8 power, premium German engineering, advanced safety, and exceptional comfort**. Clean, well-maintained GLS 550s with extensive service history like this are getting harder to find, especially here in the Pacific Northwest.
