Used 2024 Mercedes-Benz GLS for Sale near Quebec

How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 28.09% compared to this time last year, making it a favourable time to shop this model year.

There are 54 listings available, which suggests you have a reasonable amount of inventory to compare.

Is the 2024 Mercedes-Benz GLS a good car?

Yes — the 2024 Mercedes-Benz GLS earns a 5/5 user rating and an 8.5/10 expert rating. The standout strength is Safety at 10/10.

The GLS is a large three-row luxury SUV that leans into comfort and prestige, and the 2024 refresh adds minor styling changes, fresh colours and trim, more standard equipment, enhanced off-roading technology, and an updated MBUX system. That lines up well with its role as an upscale family hauler that still feels polished and current.

The main trade-offs are the steep price of entry, third-row seat access, and touch-sensing controls. The AMG Line Package can also make entry and exit less convenient.

With 37.0% of listings marked as good or great deals, there is some room to shop selectively.

Is the 2024 Mercedes-Benz GLS reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The GLS is presented as a refined, well-rounded luxury SUV with comfortable ride quality, premium interior materials, and easy-to-use technology. Its powertrain is described as smooth, quiet, and well calibrated, and the expert evaluation also highlights strong ADAS behaviour and a generally reassuring driving experience.

The performance notes also point to a mild-hybrid system that adds instant torque off the line, which should help the SUV feel responsive in everyday driving. Mercedes also includes a first scheduled maintenance visit on the house, which is a useful ownership perk.

For used buyers, the main long-term risk is less about outright mechanical weakness and more about living with a complex, expensive luxury SUV, so condition and maintenance history matter.

What should I look for when buying a used 2024 Mercedes-Benz GLS?

Key things to evaluate:

• Trim level: The GLS 450 is the most affordable version and comes with a turbocharged 3.0-litre inline six-cylinder engine with mild-hybrid technology. The GLS 580, AMG GLS 63, and Maybach GLS 600 move to a twin-turbo V8 with MHEV, while the GLS 450 can be fitted with AMG Line and Exclusive Trim Packages, an Acoustic Comfort Package, 22-inch wheels, leather upholstery, wood trim, and artificial leather on the dashboard and door panels. The second-row captain’s chairs are a no-charge option in place of the standard bench seat.
• Powertrain: The GLS 450’s 375 horsepower and 369 pound-feet of torque deliver smooth, silky acceleration, and the mild-hybrid system adds an instant 148 lb-ft of torque when you step on the accelerator. It uses a nine-speed automatic transmission and all-wheel drive, with Eco, Comfort, Sport, and Individual driving modes.
• Safety package: Safety comes standard, with more than 20 significant safety features. The suite includes forward-collision warning, lane-departure warning with haptic feedback, lane-keeping assist, adaptive cruise control, and lane-centring assist. You can adjust many of the advanced driver-assistance systems through MBUX, including sensitivity and alert settings.
• Infotainment: The GLS uses a 12.3-inch digital instrumentation panel and a 12.3-inch infotainment touchscreen. The updated MBUX system adds improved graphics, Classic, Sporty, and Discreet themes, plus Navigation, Assistance, and Service modes. It also includes intuitive touchscreen operation, natural voice recognition, augmented reality navigation, and a standard Burmester surround-sound system with Dolby Atmos technology.
• Fuel efficiency: The official fuel economy rating is 11.3 litres per 100 kilometres in combined driving, and the evaluation loop returned 11.8 L/100 km.

Which 2024 Mercedes-Benz GLS trim should I buy?

The 2024 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 starting point because it delivers the core GLS experience: smooth six-cylinder power, strong standard technology, and the comfort-focused character that defines the model. If you want the most balanced version of the SUV without chasing extra power, this is the one to start with.
• GLS 580: This trim steps up to the twin-turbo V8 family and is the one to consider if you want more power and the added capability of the available Off-Road Package, which includes underbody protection, up to 3 centimetres of added ground clearance, and improved water fording capability.
• AMG GLS 63: Choose this if you want the performance-oriented version of the GLS lineup and are willing to pay for the extra power and more aggressive character.
• Maybach GLS 600: This is the most luxurious expression of the GLS nameplate and suits you if your priority is maximum prestige and comfort rather than value.

Safety comes standard across the GLS lineup, so you are not forced into a higher trim just to get the core driver-assistance suite.

Is now a good time to buy a used 2024 Mercedes-Benz GLS?

This looks like a moderate, selective buyer’s market, so you can afford to be choosy while still finding worthwhile listings.

• Deal availability: 37.0% of listings are priced as good or great deals.
• Inventory: There are 54 listings available.
• Price trend: Prices have softened 28.09% compared with last year.

If you find a listing below $92,821 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2024 Mercedes-Benz GLS's resale value?

The current average of $92,821 CAD sits slightly below last year's $129,072 CAD.

That drop suggests the market has already adjusted downward, which can help you as a buyer today but may also mean less room for a future seller to recover a premium quickly. If you buy at the right price and keep the SUV in strong condition, you may be better positioned than someone who paid closer to last year’s average.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2024 Mercedes-Benz GLS safe?

The 2024 Mercedes-Benz GLS earns a 10/10 safety score from our experts.

It comes standard with a broad suite of advanced driver-assistance systems, including forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centring assist. You can also tailor many of the settings through MBUX, which helps reduce annoyance and lets you tune the alerts to your preference.

The expert evaluation notes that the systems work smoothly and transparently, with subtle steering and speed adjustments and strong overall behaviour on bends, curves, and ramps. A single lane-centring interruption was noted on a challenging road layout, but the overall safety impression remains very strong.

Should I buy a 2024 Mercedes-Benz GLS or consider a different year?

If you're weighing the 2024 against nearby model years, here's how to think about it:

Choose the 2024 if:

• 37.0% of listings are priced as good or great deals.
• Price trend: Prices have softened 28.09% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• This year brings minor styling modifications, fresh colours and trim, more standard equipment, enhanced off-roading technology, and an updated MBUX infotainment system.

The bottom line: If you want the freshest version of this luxury SUV with updated tech and a softer used-market price, the 2024 is the smart path. If you are mainly focused on stretching your budget, a nearby model year may still make sense, but the 2024’s combination of updates and lower pricing makes it the more compelling choice for many shoppers.
