Used 2024 Mercedes-Benz GLS for Sale near Illinois

How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 11.55% compared to this time last year, making it a favorable time to shop this model year.

There are 1,427 listings available, which suggests solid inventory availability for shoppers comparing trims and prices.

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 three-row luxury SUV that was refreshed for the year with minor styling modifications, fresh colors and trim, more standard equipment, enhanced off-roading technology, and a new version of its MBUX infotainment system. That combination supports its appeal if you want a substantial, upscale SUV that feels polished and current without changing its core mission.

The trade-offs are clear: the AMG Line Package impedes entry and exit, third-row seat access is a challenge, and touch-sensing controls remain frustrating. Even so, the GLS still fits buyers who want comfort, premium interior materials, and easy-to-use technology in a high-end family hauler.

34.9% of listings are priced as good or great deals, which gives you 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 described as a vehicle that won’t fail to meet your expectations, and the expert evaluation emphasizes its quiet, smooth, and well-calibrated driving character. Its mild-hybrid straight-six setup is presented as a strong fit because it delivers plenty of power without the added cost of ownership or more frequent fuel stops.

The ownership picture also benefits from the model’s broad standard equipment and the way its systems are tuned to work transparently in daily driving. If you’re buying used, the main long-term risk is less about basic dependability and more about living with expensive luxury-SUV complexity and the quirks of its touch-sensitive controls.

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

Accident-free inventory is excellent at 93.5% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially on a luxury SUV with advanced electronics and multiple comfort systems. Pay close attention to how the cabin controls, driver-assistance features, and third-row access work in real-world use, since those are the areas most likely to affect your day-to-day satisfaction.

Key things to evaluate:

• Trim level: The GLS 450 is the most affordable version and is the best-value starting point if you want the core GLS experience without stepping up to the more expensive V8 models. The GLS 580, AMG GLS 63, and Maybach GLS 600 add more power and a more upscale or performance-focused feel, while the GLS 450 already delivers the premium interior materials, comfortable ride, and easy-to-use technology that define the model.
• Powertrain: The GLS 450 uses a turbocharged 3.0-liter inline six-cylinder engine with mild-hybrid technology, and the expert evaluation says you do not need the extra power of the V8 to enjoy the SUV. It delivers smooth, swift acceleration, and the mild-hybrid system adds an instant torque boost off the line.
• Safety package: Safety comes standard, and the GLS includes a broad set of advanced driver-assistance systems that you can adjust through MBUX. The expert evaluation highlights forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centering assist, all of which operate smoothly and transparently.
• Infotainment: The GLS uses a 12.3-inch digital instrument panel and a 12.3-inch infotainment touchscreen, along with improved graphics and helpful navigation features. Wireless smartphone integration is not stated in the provided data, so focus instead on how the dual-screen layout, voice recognition, and augmented-reality navigation work during your test drive.
• Fuel efficiency: The GLS 450 is rated at 21 mpg in combined driving, which is a useful benchmark for a large luxury SUV with all-wheel drive and strong performance.

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 already gives you the GLS’s core strengths: a smooth mild-hybrid inline-six, strong acceleration, a refined cabin, and the latest MBUX system. If you want the most balanced mix of comfort, technology, and efficiency, this is the trim to start with.
• GLS 580: This trim steps up to a twin-turbo V8 with mild-hybrid support and is the one 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. Choose it if you want more power and the most off-road-oriented setup mentioned in the data.
• AMG GLS 63: This is the performance-focused choice in the lineup, aimed at buyers who want the most aggressive version of the GLS experience. The provided data identifies it as part of the higher-output model series, but the GLS 450 remains the smarter pick if you care more about value than maximum performance.
• Maybach GLS 600: This is the most luxurious version of the group and suits you if your priority is top-tier prestige and comfort rather than value. It sits at the top of the lineup and is best for shoppers who want the most exclusive GLS experience.

Safety comes standard across the lineup, so you can shop trims based on power and luxury without giving up the model’s core driver-assistance coverage.

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

This is a moderate market for selective buyers, so you can shop carefully and still find worthwhile listings.

• Deal availability: 34.9% of listings are priced as good or great deals.
• Inventory: There are 1,427 listings available.
• Price trend: Prices have softened 11.55% compared with last year.
• Clean inventory: 93.5% of listings are accident-free.

If you find a listing below $72,572, 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 $72,596 sits slightly below last year's $82,079.

That decline suggests the market has moved in buyers’ favor, which can make the GLS easier to shop now than it was a year ago. For a future seller, the key takeaway is that pricing pressure has already reset the market lower, so resale value will depend heavily on condition, mileage, and how well the vehicle has been maintained.

Because this model still carries strong appeal as a large, upscale three-row SUV, well-kept examples should remain attractive to shoppers who want comfort and technology in one package. 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 Safety Pick+ recognition and five-star ratings from NHTSA.

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

Safety comes standard, and the GLS includes a large suite of advanced driver-assistance systems that you can tailor through MBUX. The expert evaluation highlights forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centering assist, all of which worked smoothly during testing.

One caveat is that the lane-centering assist briefly turned off in a specific low-speed intersection scenario, so you should still stay engaged even with the driver-assistance systems active. Overall, though, the safety package is a major strength and 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:

• 34.9% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 93.5% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 11.55% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2024 refresh adds minor styling changes, more standard equipment, enhanced off-roading technology, and a new MBUX infotainment system.

The bottom line: If you want the most current version of this large three-row luxury SUV, the 2024 is the right target because it brings meaningful updates without changing the GLS formula. If your priority is simply finding the lowest possible price, a nearby model year may be worth comparing, but the 2024’s refreshed equipment and strong market conditions make it the better all-around buy for most shoppers.
