Used 2024 Mercedes-Benz GLS for SaleNationwide

How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 19.49% compared to this time last year, making it a favourable time to shop this model year.

There are 56 listings available, which suggests a modest amount of inventory for shoppers 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.

It is a large luxury SUV that leans into comfort, refinement, and a strong sense of occasion, while the refreshed model adds minor styling changes, more standard equipment, enhanced off-roading technology, and an updated MBUX system. The cabin strengths are clear: it is comfortable, uses premium interior materials, and offers easy-to-use technology.

The 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 30.4% of listings marked as good or great deals, there is a meaningful share of attractive inventory to consider.

Is the 2024 Mercedes-Benz GLS reliable?

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

The 2024 Mercedes-Benz GLS is presented as a well-rounded luxury SUV that does a lot well rather than excelling at only one task. Its smooth, quiet powertrain, strong standard equipment, and polished driving manners support the case for dependable day-to-day use. The performance notes also point to a powertrain that feels lively from a stop and delivers smooth, seamless acceleration.

Mercedes also positions the GLS as a vehicle with impressive efficiency for its class, which can help reduce the burden of ownership over time. For used buyers, the main long-term risk is less about basic competence and more about living with its size, complexity, and premium running costs.

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 brings the core luxury experience with premium interior materials, easy-to-use technology, and the refreshed design details. Higher versions add more power and, in the case of the GLS 580, an Off-Road Package with underbody protection, added ground clearance, and improved water fording capability.
• Powertrain: The GLS 450 uses a turbocharged 3.0-litre inline six-cylinder engine with mild-hybrid technology, while higher versions use a twin-turbo V8 with mild-hybrid assistance. The GLS 450 is described as smooth, quiet, quick, and efficient, with plenty of power for everyday use.
• Safety package: Safety comes standard, with more than 20 significant safety features and adjustable advanced driver-assistance systems through MBUX. The suite includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centring assist.
• Infotainment: The GLS uses the latest MBUX system with a 12.3-inch digital instrument panel and a 12.3-inch infotainment touchscreen. It includes improved graphics, intuitive touchscreen operation, natural voice recognition, and augmented reality navigation.
• 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, premium materials, and the updated MBUX system.
• GLS 580: Choose this if you want more power and the added capability of the Off-Road Package, which includes underbody protection, extra ground clearance, and improved water fording capability.
• AMG GLS 63: This is the performance-focused choice in the range, aimed at buyers who want the most aggressive version of the GLS lineup.
• Maybach GLS 600: This is the most luxurious option, suited to buyers who want the highest level of prestige and comfort in the GLS family.

Safety comes standard across the range, and the advanced driver-assistance systems can be adjusted 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 shop carefully and still find worthwhile opportunities.

• Deal availability: 30.4% of listings are priced as good or great deals.
• Inventory: There are 56 listings available.
• Price trend: Prices have softened 19.49% compared with last year.

If you find a listing below $95,878 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 $96,984 CAD sits slightly below last year's $120,458 CAD.

That price movement suggests the market has already adjusted downward, which can make the GLS more appealing to used buyers today. For a future seller, that also means resale value may depend heavily on condition, mileage, and how well the vehicle is equipped. A well-kept example with desirable equipment should still attract attention, but the current trend shows there is less pricing momentum than there was a year ago.

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 more than 20 significant safety features, and the advanced driver-assistance systems can be adjusted through MBUX so you can tailor sensitivity and alerts to your preference. The suite includes forward-collision warning, lane-departure warning with haptic feedback, lane-keeping assist, adaptive cruise control, and lane-centring assist.

In testing, the systems were described as subtle, smooth, and transparent, with only a single moment when lane-centring assist briefly turned off on a challenging road layout. That said, the overall safety package is a major strength, and it is one of the GLS’s defining advantages.

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:

• 30.4% of listings are priced as good or great deals.
• Price trend: Prices have softened 19.49% 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: The 2024 GLS is the right pick if you want the refreshed version with updated styling, more standard equipment, and the latest MBUX system. If you are shopping with a tighter budget, the softened pricing and decent deal availability make this a sensible year to target, especially if you can find a well-equipped example near the low end of the range.
