New & Used 2027 Mercedes-Benz GLS for Sale nearAlbany, NY

Is the 2027 Mercedes-Benz GLS a good car?

The 2027 Mercedes-Benz GLS earns an expert rating of 7.7/10. The standout strength is Performance at 9/10.

It is aimed at you if you want extra space and towing capacity in a luxury SUV, and Mercedes positions it as the SUV equivalent of the brand’s flagship S-Class sedan. That helps explain why it can be equipped with virtually every feature in the automaker’s catalog, and why the 2027 refresh adds updated styling, powertrains, and tech features.

The trade-offs are that the design may not appeal to everyone and some ergonomic issues remain. Even so, the GLS was already a well-executed luxury SUV, and the updates do not need to transform it to keep it competitive.

Good and great deals account for 33.3% of listings, which suggests there is still some room for selective shoppers to find value.

Is the 2027 Mercedes-Benz GLS reliable?

The 2027 Mercedes-Benz GLS is presented as a refined, well-executed luxury SUV, and the updated powertrains are described as improving responsiveness while reducing noise, vibration, and harshness. Mercedes also says the six-cylinder GLS 450 is all the engine drivers need, which points to a powertrain lineup that should be straightforward for everyday use.

The performance hardware is substantial, but the core setup is conventional for the segment: an integrated starter/generator electric motor, a nine-speed automatic transmission, and 4Matic all-wheel drive. Mercedes also says the updated engines are designed to improve responsiveness and refinement, which is a good sign for long-term drivability.

Mercedes does not mention a maintenance perk in the provided material. For used buyers, the main long-term ownership risk is that the GLS’s complexity and high-end equipment can make repairs and upkeep more expensive if something goes wrong.

What should I look for when buying a used 2027 Mercedes-Benz GLS?

Accident-free inventory is excellent at 98% — clean inventory, standard diligence applies.

You should still run a history report and inspect the vehicle carefully, especially if it has the larger wheels or more complex option content. Pay close attention to cabin condition, electronic features, and whether the equipment you want is actually present, since the GLS can be configured very differently from one example to the next.

Key things to evaluate:

• Trim level: The standard GLS 450 4Matic and GLS 580 4Matic are joined by the AMG GLS 63 performance model and the ultra-luxury Maybach GLS 680. The base GLS 450 is the value-oriented choice, while the Maybach and AMG versions add more specialized character and equipment.
• Powertrain: The GLS 450 uses a turbocharged 3.0-liter inline-six with 375 horsepower and 413 pound-feet of torque, while the GLS 580 uses a twin-turbo 4.0-liter V8 with 530 hp and 553 lb-ft. All models use an integrated starter/generator electric motor, a nine-speed automatic transmission, and 4Matic AWD.
• Safety package: Standard driver-assistance features include lane-keep assist, forward-collision warning, automatic emergency braking, blind-spot monitors, traffic-sign and speed-limit recognition, and adaptive cruise control with stop-and-go functionality. Optional features include steering assist, lane-change assist, parking assist, and a surround-view camera system.
• Infotainment: The standard Superscreen uses three 12.3-inch screens, and the system retains wireless Apple CarPlay and Android Auto. Mercedes’ MB.OS-based MBUX system is new, and the front-passenger screen can show videos and basic games.
• Fuel efficiency: The GLS 450 is expected to achieve 21 mpg combined, 19 mpg city, and 24 mpg highway. Mercedes did not provide 2027 estimates for the V8 models, but the prior-year figures were 16 mpg combined for the GLS 580, 17 mpg combined for the AMG GLS 63, and 15 mpg combined for the Maybach model.

Which 2027 Mercedes-Benz GLS trim should I buy?

The 2027 Mercedes-Benz GLS is offered in 4 trim levels: GLS 450 4Matic, GLS 580 4Matic, AMG GLS 63, and Maybach GLS 680.

Here's the short version:

• GLS 450 4Matic: This is the best-value choice if you want the GLS experience without pushing into six-figure territory. It still gives you the updated styling, the new Superscreen, the standard driver-assistance suite, and the six-cylinder powertrain that Mercedes says is all most drivers need.
• GLS 580 4Matic: This is the step-up pick if you want stronger performance and more effortless acceleration. It adds the twin-turbo V8 and is the right choice if you want more muscle without going all the way to the AMG or Maybach models.
• AMG GLS 63: Choose this if you want the performance-focused version. It uses a higher-output V8, a performance-tuned transmission and suspension, a limited-slip differential, and beefier brakes.
• Maybach GLS 680: This is the ultra-luxury choice if you want the most exclusive version of the GLS. It stands apart with extra chrome, 22-inch monobloc wheels, and the most upscale presentation.

The standard safety package includes lane-keep assist, forward-collision warning, automatic emergency braking, blind-spot monitors, traffic-sign and speed-limit recognition, and adaptive cruise control.

Is the 2027 Mercedes-Benz GLS safe?

The 2027 Mercedes-Benz GLS does not have crash-test ratings listed in the provided material.

It earns an 8/10 safety score from our experts.

Standard driver-assistance features include lane-keep assist, forward-collision warning, automatic emergency braking, blind-spot monitors, traffic-sign and speed-limit recognition, and adaptive cruise control with stop-and-go functionality. Optional features available at launch include steering assist, lane-change assist, parking assist, and a surround-view camera system.

Mercedes also says the GLS’ sensor suite can support a more advanced driver-assistance system that will arrive later as an over-the-air update, pending regulatory approval. Pre-Safe can close the windows and tighten the seatbelts in a collision, and Pre-Safe Sound plays pink noise through the audio system to help reduce the risk of hearing loss.

Should I buy a 2027 Mercedes-Benz GLS or consider a different year?

If you're weighing the 2027 against nearby model years, here's how to think about it:

Choose the 2027 if:

• 33.3% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 98% — clean inventory, standard diligence applies.
• The 2027 brings updated styling, powertrains, and tech features to an already well-executed luxury SUV.

Consider the 2026 if:

• It offers the roomiest Mercedes SUV experience with strong comfort, luxury, and manageable dimensions.

The bottom line: If you want the newest GLS with the refreshed design and updated tech, the 2027 is the one to target. If you are more price-sensitive and want the core GLS strengths without paying for the latest updates, the 2026 remains a sensible alternative.
