New & Used 2026 Mercedes-Benz GLS for Sale nearKodiak, AK

Is the 2026 Mercedes-Benz GLS a good car?

The 2026 Mercedes-Benz GLS earns an 7.83/10 expert rating. The model scores 9/10 across Look and feel and Technology.

It is aimed at you if you want a three-row SUV with a three-pointed star on the grille, and it backs that up with more passenger room and cargo space than any other Mercedes model. The cabin is a highlight, with premium interior materials, strong refinement, and a luxury feel that matches its role at the top of the brand’s SUV lineup. It also delivers a large-SUV experience without feeling unwieldy, thanks to manageable dimensions and rewarding driving dynamics.

The trade-offs are that fuel economy is unimpressive, third-row access is not especially easy, and cargo space trails some rivals. Even so, the GLS makes a strong case if you value comfort, technology, and everyday drivability in a full-size luxury SUV.

Good and great deals account for 35.0% of listings, which gives you a moderate amount of market flexibility.

Is the 2026 Mercedes-Benz GLS reliable?

The 2026 Mercedes-Benz GLS is presented as a comfortable, refined luxury SUV with a strong emphasis on everyday usability, and its turbocharged inline-six powertrain is described as the least powerful engine in the lineup rather than a weak point in durability. The expert evaluation also notes that the GLS feels composed and quiet, with a smooth ride and solid dynamics that support long-term satisfaction.

Its performance content points to a standard Airmatic adaptive suspension and a powertrain that can feel delayed or lurchy in Comfort mode, though Sport mode reduces those traits. The cost-effectiveness commentary also suggests that a base GLS 450 4Matic should satisfy many buyers who prioritize a quiet cabin, modern tech, and responsive driving dynamics.

For used buyers, the main long-term ownership risk is that this is a complex luxury SUV, so you should expect higher upkeep sensitivity than you would from a simpler mainstream model.

What should I look for when buying a used 2026 Mercedes-Benz GLS?

Accident-free inventory is excellent at 97.3% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially on a luxury SUV with advanced electronics and a long feature list. Focus on cabin condition, suspension behavior, and how smoothly the powertrain responds in everyday driving, since those are the areas most likely to shape your ownership experience.

Key things to evaluate:

• Trim level: The GLS 450 is the base version, and it comes with artificial leather upholstery, while higher trims add more upscale materials and equipment. The Manufaktur Edition Package on the test vehicle adds 21-inch AMG wheels, AMG Line Exterior Package, Night Package, Exclusive Package with massaging front and heated second-row captain’s chairs, exclusive paint colors, premium leather, Natural Grain Grey Oak interior wood trim, and a black headliner.
• Powertrain: The GLS 450 uses a turbocharged 3.0-liter inline-six with mild-hybrid assist, making 375 horsepower and 369 pound-feet of torque. It pairs with a nine-speed automatic transmission and standard 4Matic all-wheel drive, and it is EPA-rated at 21 mpg combined.
• Safety package: Nearly 40 safety and driver-assistance systems are standard, including Pre-Safe, Crosswind Assist, Active Emergency Stop Assist, and Car-to-X Communication. Front and rear parking sensors and a surround-view camera system are also standard, while rear-seat side-impact airbags are optional.
• Infotainment: The GLS uses dual 12.3-inch displays with MBUX. Wireless Apple CarPlay and Android Auto are standard, along with navigation with augmented reality enhancement and a standard Burmester surround-sound system with Dolby Atmos technology.
• Fuel efficiency: The GLS 450 is EPA-rated at 21 mpg combined, and the test route returned 19.4 mpg.

Which 2026 Mercedes-Benz GLS trim should I buy?

The 2026 Mercedes-Benz GLS is offered in 4 trim levels: GLS 450, GLS 580, AMG GLS 63, and Maybach GLS 600.

Here's the short version:

• GLS 450: This is the best-value choice if you want the GLS experience without chasing the highest price. It gives you the core strengths of the model: a premium cabin, standard 4Matic AWD, a turbocharged inline-six, Airmatic adaptive suspension, and the full MBUX tech suite.
• GLS 580: Choose this if you want more power and a more upscale feel than the GLS 450, while staying within the mainstream GLS lineup. It sits above the base model and is the better fit if you expect to use the SUV as a long-distance luxury cruiser with extra performance reserve.
• AMG GLS 63: This is the performance-focused choice for buyers who want the most aggressive version of the GLS. It is the trim to consider if you care most about stronger acceleration and a more athletic character.
• Maybach GLS 600: This is the luxury-first choice if your priority is maximum opulence and exclusivity. It sits at the top of the range and is the trim for buyers who want the most lavish GLS experience.

Rear-seat side-impact airbags are optional rather than standard, so that is worth checking if safety equipment is a priority for your shopping list.

Is the 2026 Mercedes-Benz GLS safe?

The 2026 Mercedes-Benz GLS does not have a crash-test rating cited here, but it comes with nearly 40 standard safety and driver-assistance systems, including Pre-Safe, Crosswind Assist, Active Emergency Stop Assist, and Car-to-X Communication.

It earns a 7/10 safety score from our experts.

The standard safety suite also includes front and rear parking sensors and a surround-view camera system. One important caveat is that rear-seat side-impact airbags are optional rather than standard, and the hands-on driver-assistance system is not a hands-free setup. The expert evaluation also notes that the steering-assist tech can wander in sharper curves and that its curve-speed reduction can be overly cautious.

Should I buy a 2026 Mercedes-Benz GLS or consider a different year?

If you're weighing the 2026 against nearby model years, here's how to think about it:

Choose the 2026 if:

• 35.0% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 97.3% — clean inventory, standard diligence applies.
• It adds the new-for-2026 Manufaktur Edition Package, which brings extra style and luxury touches to the GLS 450.

The bottom line: The 2026 GLS is a strong pick if you want the latest version of this spacious, refined, and tech-rich three-row Mercedes SUV. If you are price-sensitive, a nearby model year may deliver a similar ownership experience with a lower entry cost, but the 2026 is the better choice if you want the newest available updates and a healthy share of clean inventory.
