How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 11.31% compared to this time last year, making it a favorable time to shop this model year.

There are 1,433 listings available, which gives you a solid 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 overview and expert evaluation both point to a large three-row luxury SUV that feels polished, current, and especially well suited to buyers who want comfort, premium interior materials, and easy-to-use technology. It is also described as a strong fit if you want a substantial, upscale SUV that delivers the gratification expected from something this expensive.

The trade-offs are real: the AMG Line Package impedes entry and exit, third-row seat access is a challenge, and touch-sensing controls remain frustrating.

With 33.8% of listings priced as good or great deals, you have a decent chance of finding a competitive offer if you shop carefully.

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 that combines comfort, premium materials, and technology in a way that should age well for used buyers. The expert evaluation also describes the driving experience as quiet, quick, and well calibrated, which supports the sense that the vehicle is engineered to feel composed over time.

Its performance notes emphasize smooth, silky power delivery, seamless acceleration, and an adaptive air suspension that helps the tall SUV stay controlled. The technology package is also described as intuitive and genuinely helpful, which matters because a well-executed cabin can make long-term ownership feel easier.

If you buy used, your main long-term risk is living with a complex luxury SUV whose touch-sensitive controls and access compromises may become daily annoyances if the vehicle has been poorly maintained or heavily optioned.

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

Accident-free inventory is excellent at 93.9% — clean inventory, standard diligence applies.

You should still run a history report and prioritize a pre-purchase inspection, especially on a luxury SUV with advanced electronics and multiple comfort systems. Focus on how the cabin, controls, and seating access feel in person, since the GLS’s biggest drawbacks are usability-related rather than mechanical.

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 you up the ladder with more power and a more upscale presentation. The GLS 450 is the best-value starting point if you want the core GLS experience without paying for extra performance you may not need.
• Powertrain: The GLS 450 uses a turbocharged 3.0-liter inline six-cylinder engine with mild-hybrid technology, while the higher models use a twin-turbo V8 with mild-hybrid technology. The GLS 450 delivers 375 horsepower and 369 pound-feet of torque, plus smooth acceleration and a combined rating of 21 mpg.
• Safety package: Safety comes standard, and the SUV includes more than 20 significant safety features. The 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-centering assist.
• Infotainment: The GLS uses a 12.3-inch digital instrument panel and a 12.3-inch infotainment touchscreen, along with improved graphics, intuitive touchscreen operation, natural voice recognition, and augmented reality navigation. Be sure to test the touch-sensitive steering-wheel controls and center-console touchpad, since they can be distracting.
• Fuel efficiency: The GLS 450 is rated at 21 mpg in combined driving, and the expert evaluation recorded 19.9 mpg on a mixed evaluation loop.

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 because it delivers the core GLS experience with the turbocharged inline-six, mild-hybrid assistance, strong performance, and the same upscale cabin feel that defines the model. If you want the GLS for comfort, technology, and everyday luxury rather than maximum power, this is the trim to target.
• GLS 580: This step-up model is for you if you want the twin-turbo V8 experience and are willing to pay more for extra power. It also stands out because it is the model explicitly tied to the Off-Road Package, which adds underbody protection, up to 1.2 inches of extra ground clearance, and improved water fording capability.
• AMG GLS 63: This is the performance-focused choice for buyers who want the most aggressive version of the GLS lineup. The available information identifies it as part of the higher-output V8 family, so it suits you if performance matters more than value.
• Maybach GLS 600: This is the most luxurious version in the lineup and is aimed at buyers who want the highest level of prestige and comfort. If you want the GLS at its most opulent, this is the trim to consider.

Safety comes standard across the lineup, and the driver-assistance systems can be adjusted through MBUX.

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

This is a moderate buyer’s market, so you can shop selectively without expecting every listing to be a bargain.

• Deal availability: 33.8% of listings are priced as good or great deals.
• Inventory: There are 1,433 listings available.
• Price trend: Prices have softened 11.31% compared with last year.
• Clean inventory: 93.9% of listings are accident-free.

If you find a listing below $72,547, 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 $72,725 sits slightly below last year's $82,001.

That decline suggests the market has become more favorable for buyers, but it also means a future seller may face a softer pricing environment than owners saw a year ago. If you buy now, you are entering at a lower average price point than last year, which can help reduce depreciation exposure compared with a peak-price purchase.

The GLS still has the kind of broad appeal that supports demand: it is a large, upscale three-row SUV with strong comfort, technology, and luxury credentials. That should help it remain attractive to used shoppers who want a premium family hauler.

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.

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 can be adjusted through MBUX. The system includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centering assist, and the expert evaluation says these features operate smoothly and transparently.

The only caveat surfaced in testing is that lane-centering assist briefly turned off in one unusual road situation, though it otherwise handled the evaluation route without trouble.

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:

• 33.8% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 93.9% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 11.31% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• This year brings minor styling modifications, fresh colors and trim, more standard equipment, enhanced off-roading technology, and a new version of MBUX.

The bottom line: The 2024 GLS is the better pick if you want the freshest version of this luxury SUV with strong safety, a polished cabin, and a market that has moved in your favor. If your priority is simply the lowest possible price, a nearby model year may be worth considering, but the 2024 gives you the most up-to-date package in this comparison.
