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.

It’s a large three-row luxury SUV that leans into comfort and prestige, with a comfortable ride, premium interior materials, and easy-to-use technology.

Is the 2024 Mercedes-Benz GLS reliable?

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

The 2024 GLS is presented as a vehicle that meets expectations rather than falling short of them, and its comfort-focused character, premium materials, and easy-to-use technology all support that impression. The expert evaluation also describes the GLS as quiet, quick, and perfectly calibrated, which points to a well-sorted ownership experience.

Its powertrain is described as smooth, silky, and lively from a stop, and the mild-hybrid system adds instant torque when you step on the accelerator. The technology package is also framed as intuitive and genuinely helpful, which matters because dependable day-to-day operation often comes down to systems that are easy to live with.

Mercedes also notes that the first scheduled maintenance visit is on the house.

For used buyers, the main long-term ownership risk is that this is a complex, high-end SUV, so you’ll want to be especially careful about maintenance history and how well the vehicle’s many systems have been cared for.

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 it comes with a turbocharged 3.0-litre inline six-cylinder engine with mild-hybrid technology. It can be equipped with AMG Line and Exclusive Trim Packages, plus an Acoustic Comfort Package, 22-inch wheels, leather upholstery, wood trim, and artificial leather covering 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 provide smooth, silky acceleration, and the mild-hybrid system adds an instant 148 lb-ft of torque off the line. It uses a nine-speed automatic transmission and variable 4Matic all-wheel drive. Mercedes also notes that the GLS 580 uses a twin-turbo V8 with mild-hybrid technology.
• Safety package: Safety comes standard, and the SUV includes more than 20 significant safety features. The advanced driver-assistance systems can be adjusted through MBUX, including sensitivity settings and alert preferences. The forward-collision warning system, lane-departure warning system, lane-keeping assist system, adaptive cruise control, and lane-centring assist all work smoothly, though lane-centring assist briefly turned off once during evaluation.
• Infotainment: The GLS uses Mercedes’ latest MBUX system with a 12.3-inch digital instrumentation panel and a 12.3-inch infotainment touchscreen. It includes improved graphics, Classic, Sporty, and Discreet instrumentation themes, plus Navigation, Assistance, and Service modes. The system is fast and easy to use, but the touch-sensitive steering-wheel controls and centre-console touchpad can be distracting.
• 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 choice if you want the core GLS experience without paying for extra power you may not need. It delivers smooth performance, strong efficiency for the class, and the upscale cabin and technology that define the model.
• GLS 580: Choose this if you want the twin-turbo V8 character and are willing to pay for it. It also stands out because it is exclusively available with an Off-Road Package that 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 lineup, aimed at buyers who want the most aggressive version of the GLS.
• Maybach GLS 600: This is the most luxurious version of the GLS family, for buyers who want the highest-end presentation and equipment.

The safety package is standard across the GLS lineup, and the ADAS can be tailored through MBUX.

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 picky while still finding opportunities.

• Deal availability: 16.0% of listings are priced as good or great deals.
• Inventory: There are 50 listings available.
• Price trend: Prices have softened 26.63% compared with last year.

If you find a listing below $95,833 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 $95,833 CAD sits slightly below last year's $130,622 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 resale value may depend heavily on condition, equipment, and how well the vehicle has been maintained.

Because this is a high-end SUV, well-kept examples with desirable equipment should remain easier to move than neglected ones. Strong presentation and a clean service record will matter a lot when you eventually sell.

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 Top Safety Pick+ rating from IIHS and a five-star overall rating from NHTSA, with five-star ratings in all other NHTSA tests.

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

Safety comes standard, and the GLS includes more than 20 significant safety features. The advanced driver-assistance systems can be adjusted through MBUX, including sensitivity and alert settings, and the suite includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centring assist.

The systems are described as subtle, smooth, and transparent in operation, which is exactly what you want in a large luxury SUV. The only caveat noted is that lane-centring assist briefly turned off once during evaluation.

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:

• 16.0% of listings are priced as good or great deals.
• Price trend: Prices have softened 26.63% 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 a new version of MBUX.

The bottom line: If you want the most polished version of the GLS in this price window, the 2024 model is the one to target. It combines strong safety, a high-end cabin, and meaningful updates that improve an already appealing luxury SUV. If you’re more price-sensitive, the softened market and modest inventory make it worth shopping carefully for a well-equipped example rather than stretching for the newest listing you see.
