About This 2017 Mercedes-Benz GLS 450

The GLS-Class is Mercedes-Benz's flagship SUV — the brand's answer to buyers who refuse to compromise between luxury and practicality. This particular example comes finished in a sophisticated gray exterior and has been driven an average of just under 14,000 miles per year, which is right in line with normal usage for a vehicle of this age.

2017 Mercedes-Benz GLS 450 Performance and Engine

Twin-Turbo V6 Power You Can Feel

Under the hood sits a 3.0-liter twin-turbocharged V6 engine paired with Mercedes-Benz's acclaimed 9-speed 9G-TRONIC automatic transmission. This combination produces around 362 horsepower and 369 lb-ft of torque, giving the GLS 450 genuinely quick acceleration for a vehicle of its substantial size. The 9G-TRONIC transmission shifts with silky smoothness and always seems to find the right gear whether you're merging onto Interstate 5, climbing through mountain terrain, or cruising the Pacific Coast Highway.

All-wheel drive comes standard on the GLS 450, providing confident traction year-round. Whether you're navigating rainy San Diego winters or planning weekend trips to Big Bear or Julian, the intelligent AWD system distributes torque efficiently and keeps the vehicle planted and stable. The GLS 450 is also rated to tow up to 7,500 pounds, making it a legitimate option for buyers who need to haul a boat, trailer, or recreational equipment.

Mercedes-Benz GLS 450 Features and Interior

Three Rows of Genuine Luxury

The GLS 450 is one of the few luxury SUVs on the market that can honestly claim true seven-passenger comfort — not the cramped, fold-flat compromise you find in many competitors. The second row offers generous legroom, and even adult passengers in the third row have a livable amount of space for longer drives.

The 2017 GLS 450 Sport Utility trim typically includes a panoramic sunroof, heated front and rear seats, leather upholstery, tri-zone climate control, a Harman Kardon audio system, and Mercedes-Benz's COMAND infotainment interface with navigation. Driver assistance features such as blind-spot monitoring, lane-keeping assist, active braking, and parking sensors round out a tech package that still feels remarkably current. The interior materials — real wood trim, soft-touch surfaces, and precisely stitched leather — reflect a build quality that San Diego buyers who cross-shop Lexus or Audi will immediately recognize as a step above.

Mercedes-Benz GLS Reliability and Ownership

What Owners Actually Say

The GLS 450 has earned a solid reputation among Mercedes-Benz SUV owners as one of the more dependable models in the lineup. The twin-turbo 3.0-liter V6 engine is widely regarded as a robust, refined unit with strong real-world longevity when maintained on schedule. Owners consistently praise the ride quality, power delivery, and overall build integrity.

As with any European luxury vehicle, staying current on maintenance matters — particularly oil changes using the correct specification, spark plugs at the recommended interval, and attention to the air suspension system if equipped. At just under 96,000 miles, this GLS 450 is entering a phase of ownership where a pre-purchase inspection by a qualified Mercedes-Benz technician is a smart step, and Siry Motors San Diego can help facilitate that conversation. Many GLS owners routinely drive these vehicles past 150,000 to 200,000 miles with proper care.
