New & Used 2026 Mercedes-Benz GLS for Sale near St Paul, AB

Is the 2026 Mercedes-Benz GLS a good car?

The 2026 Mercedes-Benz GLS earns a 7.8/10 expert rating. The model scores 9/10 across Look and feel and Technology.

For you, the appeal is straightforward: this is the roomiest vehicle in the Mercedes-Benz lineup, with three rows for six or seven people, up to 2,400 litres of cargo space, and a cabin that blends S-Class-style comfort with a more manageable SUV footprint. It also brings a long list of standard equipment, including heated front seats, dual 12.3-inch displays, navigation, a Burmester surround sound stereo, wireless charging, power-folding third-row seats, and a wide array of driver-assistance features.

The trade-offs are just as clear. Fuel economy is unimpressive, third-row entry and exit are a challenge, and touch-sensing controls remain a weak point. The GLS 450 4Matic is still the version many buyers are likely to be satisfied with, especially if you want luxury, technology, and everyday drivability in one package.

34.1% of listings are priced as good or great deals, which gives you a moderate amount of market leverage.

Is the 2026 Mercedes-Benz GLS reliable?

The 2026 Mercedes-Benz GLS is presented as a refined, comfortable luxury SUV with a strong standard equipment list and a powertrain that is described as smooth and rewarding in everyday driving. The turbocharged inline-six is the least powerful engine in the lineup, but it still delivers solid performance, and the standard Airmatic adaptive suspension is a major contributor to the SUV’s composed ride.

Mercedes also includes a complimentary one-year subscription to Digital Extras, which adds some ownership value up front. The GLS’s overall character suggests a premium vehicle that should feel well sorted in daily use, especially if you keep up with maintenance and accept that its complexity comes with the territory.

For used buyers, long-term ownership risk is mainly about the usual luxury-SUV costs that can come with advanced technology, air suspension, and a long list of convenience features.

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

Key things to evaluate:

• Trim level: The GLS 450 is the base version, and it already includes heated front seats, MB-Tex upholstery, a sunroof, dual 12.3-inch displays, navigation, a Burmester surround sound stereo, wireless charging, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels. Higher trims add more luxury and performance, while the AMG Line Package can make entry and exit more difficult.
• Powertrain: The GLS 450 uses a turbocharged 3.0-litre inline-six with mild-hybrid assist, making 375 horsepower and 369 pound-feet of torque through a nine-speed automatic and standard 4Matic AWD. It is the least powerful engine in the lineup, but it still delivers strong everyday performance.
• Safety package: Standard equipment includes Mercedes’s Pre-Safe and Crosswind Assist technologies, plus front and rear parking sensors, a surround-view camera system, blind spot assist, adaptive headlamps, auto high beams, parking assist, Car-to-X communication, and Exit Warning Assist. Buyers wanting hands-free highway driving assistance will not find it here.
• Infotainment: The GLS uses dual 12.3-inch displays with MBUX touchscreen functionality. Wireless Apple CarPlay and Android Auto are standard, along with augmented-reality navigation and a standard Burmester surround-sound system with Dolby Atmos technology.
• Fuel efficiency: The GLS 450 is rated at 11.3 L/100 km combined by Natural Resources Canada, and the test route returned 12.1 L/100 km.

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 for most buyers. It already comes very well equipped with heated front seats, dual 12.3-inch displays, navigation, a Burmester surround sound stereo, wireless charging, power-folding third-row seats, and a long list of safety and convenience features. If you want the core GLS experience without chasing extras, this is the trim to start with.
• GLS 580: Choose this if you want more power and more luxury headroom than the GLS 450, while staying within the same basic GLS formula.
• AMG GLS 63: This is the performance-focused choice for buyers who want the most powerful and most aggressive version of the GLS lineup.
• Maybach GLS 600: This is the opulence-first option, aimed at buyers who want the most luxurious GLS experience.

The standard safety and driver-assistance package is already extensive, but buyers should note that hands-free highway driver assistance is not included.

Is now a good time to buy a used 2026 Mercedes-Benz GLS?

• Inventory: There are 41 listings available.

Is the 2026 Mercedes-Benz GLS safe?

The 2026 Mercedes-Benz GLS earns a 7/10 safety score from our experts.

Nearly 40 safety and driver assistance systems appear on the standard equipment list, including Mercedes’s Pre-Safe and Crosswind Assist technologies. It also includes front and rear parking sensors, a surround-view camera system, blind spot assist, adaptive headlamps, auto high beams, parking assist, Car-to-X communication, and Exit Warning Assist.

The main caveat is that the GLS does not offer hands-free highway driver assistance. Instead, it uses a hands-on system with a touch-sensing steering wheel, and the system can wander on more demanding curves. That means you should treat it as an active-driver-assist setup rather than a true hands-off solution.

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:

• 34.1% of listings are priced as good or great deals.
• The 2026 GLS stands out for its huge passenger space, strong standard equipment list, and refined driving character.

The bottom line: If you want the latest version of the GLS with its full standard equipment set and you value comfort, technology, and space, the 2026 is the one to target. If price matters more than having the newest model year, a nearby used GLS may be the smarter buy, especially if you can find a well-equipped example at a better price.
