About This 2017 Mercedes-Benz GLS 450

The GLS-Class is Mercedes-Benz's flagship full-size SUV, and the 450 trim sits in a sweet spot between accessible luxury and serious performance. At just under 85,000 miles, this vehicle has plenty of life left — especially given the robust engineering Mercedes-Benz puts into the GLS platform. These trucks are routinely driven well past 150,000 miles when properly maintained, and at this mileage range they've already shed the steepest portion of their depreciation curve, meaning you're getting exceptional value per dollar spent.

Whether you're hauling your family through the Inland Empire or making a run up the 10 freeway, this GLS 450 is built to handle it all without breaking a sweat. The seven-passenger configuration, upright SUV stance, and commanding road presence make it one of the most practical luxury vehicles on the used market today.

2017 Mercedes-Benz GLS 450 Performance and Engine

Twin-Turbo V6 Power

Under the hood sits Mercedes-Benz's acclaimed 3.0-liter twin-turbocharged V6 engine, producing 362 horsepower and 369 lb-ft of torque. This is not a small-displacement engine making excuses — it's a genuinely potent powerplant that moves 5,400-plus pounds of SUV with authority. Paired with the 9-speed 9G-TRONIC automatic transmission, gear changes are nearly imperceptible and the engine always finds its optimal power band.
 

4MATIC All-Wheel Drive

The standard 4MATIC all-wheel drive system distributes power intelligently between all four wheels, giving you confident grip in rain, loose terrain, or uneven surfaces. For Southern California drivers, this means added stability on mountain passes heading up to Big Bear or through the San Bernardino Mountains — not just theoretical off-road capability.

Mercedes-Benz GLS 450 Features and Interior

The GLS 450 Sport Utility comes loaded with the premium interior touches you expect from a flagship Mercedes-Benz product. Think genuine wood trim accents, available heated and ventilated front seats, a panoramic sunroof, dual-zone or tri-zone automatic climate control, and the COMAND infotainment system with navigation. The steering wheel-mounted controls, ambient interior lighting, and available Burmester surround sound system round out a cabin that genuinely competes with living-room comfort.

Rear passengers enjoy generous legroom across both the second and third rows. Folding the third row flat opens up a massive cargo area, making this SUV as practical as it is luxurious. Power-folding rear seats, a power liftgate, and a hands-free access option make loading and unloading effortless.

Mercedes-Benz GLS 450 Reliability and Ownership

The GLS 450 built on the GL platform has earned a reputation for long-term durability when owners keep up with scheduled maintenance. The 3.0-liter biturbo V6 is one of Mercedes-Benz's most proven modern engines, sharing its core architecture across multiple GLE, GLS, and E-Class applications. Known pain points at this mileage range include air suspension components, which are worth inspecting, and routine fluid service intervals that should be verified in the service history.

Owners consistently praise the GLS 450 for its combination of family-sized utility and sports car responsiveness. The ride quality — particularly with the available AIRMATIC suspension — is often described as the closest thing to a magic carpet in a body-on-frame-adjacent package. Plan for European-vehicle maintenance costs, but understand that when maintained properly, this SUV holds up exceptionally well across high mileage.
