Used 2024 Mercedes-Benz GLS for Sale near Ontario

How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 23.90% compared to this time last year, making it a favourable time to shop this model year.

There are 56 listings available, which suggests you have some room to compare examples before you commit.

Is the 2024 Mercedes-Benz GLS a good car?

Yes — the 5/5 user rating and 8.5/10 expert rating both point to a strong overall package. The standout strength is Safety at 10/10.

The 2024 GLS is a large luxury SUV that leans into comfort, refinement, and a strong sense of occasion, while also adding minor styling changes, more standard equipment, enhanced off-roading technology, and an updated MBUX system for this model year. It is especially appealing if you want a three-row luxury SUV that feels upscale and current without losing its premium character.

The main trade-offs are that the AMG Line Package can impede entry and exit, third-row seat access is a challenge, and the touch-sensing controls may not suit everyone.

With 33.9% of listings marked as good or great deals, there is a meaningful share of inventory worth a closer look.

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 well-rounded luxury SUV that combines comfort, premium materials, and easy-to-use technology with strong day-to-day refinement. Its powertrain is described as smooth, silky, and quiet, and the mild-hybrid system helps it feel lively from a stop. The expert evaluation also highlights that the GLS does not feel like it is asking you to compromise much in normal use.

Mercedes also notes that the GLS 450’s mild-hybrid setup delivers instant torque when you accelerate, which supports smooth response and relaxed drivability. The model’s standard equipment and transparent operation add to the sense that it is engineered to be easy to live with.

For used buyers, the main long-term ownership risk is less about basic competence and more about whether the SUV’s complex luxury features and touch-sensitive controls suit your preferences over time.

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, while the GLS 580, AMG GLS 63, and Maybach GLS 600 move up the range with more powerful twin-turbo V8 setups. The GLS 450’s cabin can be fitted with AMG Line and Exclusive Trim Packages, plus an Acoustic Comfort Package, 22-inch wheels, leather upholstery, wood trim, and artificial leather on the dashboard and door panels. If you want easier access and a more straightforward ownership experience, pay close attention to whether the AMG Line Package is fitted, since it can impede entry and exit.
• Powertrain: The GLS 450 uses a turbocharged 3.0-litre inline six-cylinder engine with mild-hybrid technology, while the higher versions use a twin-turbo V8 with mild-hybrid assistance. The GLS 450 delivers 375 horsepower and 369 pound-feet of torque, with smooth acceleration and an instant torque boost from the integrated starter-generator. Mercedes says it reaches 100 km/h in 6.1 seconds.
• Safety package: Safety comes standard, and the GLS includes a broad set of advanced driver-assistance systems that can be adjusted through MBUX. The suite includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centring assist. You should also note that the lane-centring assist briefly turned off once during evaluation.
• Infotainment: The GLS uses a 12.3-inch digital instrumentation panel and a 12.3-inch infotainment touchscreen, along with improved graphics, Classic, Sporty, and Discreet themes, and Navigation, Assistance, and Service modes. It also offers intuitive touchscreen operation, natural voice recognition, and augmented reality navigation. Be aware that touch-sensitive controls on the steering wheel and centre console can be distracting.
• Fuel efficiency: The official fuel economy rating is 11.3 L/100 km 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 power, strong comfort, premium materials, and the updated MBUX system without pushing you into the highest price brackets. It is the trim that best matches the model’s comfort-first character.
• GLS 580: Choose this if you want the V8 experience and the added capability that comes with it. It is also the only version explicitly tied to the Off-Road Package, which adds underbody protection, up to 3 centimetres of extra ground clearance, and improved water fording capability.
• AMG GLS 63: This is the performance-focused choice in the range for buyers who want the most aggressive character.
• Maybach GLS 600: Pick this if your priority is maximum luxury and presence rather than value.

The standard safety equipment is a strong point across the range, so your decision should mostly come down to how much power, luxury, and off-road capability you want.

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

This is a moderate, selective buyer’s market, so you can be choosy if you shop carefully.

• Deal availability: 33.9% of listings are priced as good or great deals.
• Inventory: There are 56 listings available.
• Price trend: Prices have softened 23.90% compared with last year.

If you find a listing below $95,821 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 $95,944 CAD sits slightly below last year's $126,080 CAD.

That price drop suggests the market has already adjusted downward, which can make the GLS more attractive to used buyers today. For a future seller, it also means you should expect resale value to depend heavily on condition, equipment, and how well the vehicle has been maintained.

Because the model sits in the luxury SUV segment and offers strong standard equipment, well-kept examples should still draw interest. 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 top marks from both major crash-test bodies, including Top Safety Pick+ recognition from IIHS and five-star ratings from NHTSA.

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

Safety comes standard, and the GLS includes a broad suite of advanced driver-assistance systems that you can adjust through MBUX. The standard features highlighted in testing include forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centring assist.

The expert evaluation also notes that the systems work smoothly and transparently in real-world driving, with subtle steering and speed adjustments. One caveat is that lane-centring assist briefly turned off once during testing.

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:

• 33.9% of listings are priced as good or great deals.
• Price trend: Prices have softened 23.90% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• This year brings minor styling modifications, more standard equipment, enhanced off-roading technology, and an updated MBUX infotainment system.

The bottom line: If you want the most current version of this luxury three-row SUV, the 2024 is the one to target because it combines updated tech, strong safety, and a softer market than last year. If you are especially price-sensitive, you can use the current market softness to focus on the lowest-priced examples and be selective about trim and equipment.
