Used 2024 Mercedes-Benz GLS for Sale nearChicago, IL

How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 11.72% compared to this time last year, making it a favorable time to shop this model year.

There are 1,421 listings available, which gives you a solid amount of inventory to compare.

Is the 2024 Mercedes-Benz GLS a good car?

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

The 2024 GLS is a large three-row luxury SUV that was refreshed with minor styling changes, fresh colors and trim, more standard equipment, enhanced off-roading technology, and a new version of MBUX. That lines up with its appeal as a refined, upscale SUV that feels substantial and current without changing its core mission.

The main trade-offs are the AMG Line Package’s effect on entry and exit, the challenge of third-row access, and touch-sensing controls that can frustrate you in daily use. Even so, the GLS still makes sense if you want a premium, comfort-focused three-row SUV with strong technology and a polished feel.

37.2% of listings are priced as good or great deals, which suggests there are worthwhile opportunities 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 vehicle that should meet expectations rather than disappoint them, and the expert evaluation emphasizes its comfort, premium interior materials, and easy-to-use technology. Its powertrain is described as smooth, silky, and quick, and the mild-hybrid setup adds immediate torque off the line.

The cost-effectiveness notes also reinforce that the GLS 450 delivers rewarding driving dynamics and impressive efficiency for the segment. For used buyers, the main long-term ownership risk is less about basic competence and more about living with a complex luxury SUV, so condition and maintenance history matter.

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 history report and prioritize a pre-purchase inspection, especially on a luxury SUV with advanced driver-assistance systems and multiple electronic interfaces. Pay close attention to how the cabin controls operate, how the third row and entry points feel in real use, and whether the vehicle’s condition matches its premium positioning.

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 sit higher in the lineup. The GLS 450’s setup emphasizes comfort, premium materials, and easy-to-live-with luxury, while the more expensive versions add more power and a more exclusive feel.
• Powertrain: The GLS 450 uses a turbocharged 3.0-liter inline six-cylinder engine with mild-hybrid technology, while the higher model series use a twin-turbo V8 with mild-hybrid technology. The GLS 450 is described as smooth, silky, and quick, with 375 horsepower, 369 pound-feet of torque, and a 21 mpg combined rating.
• Safety package: Safety comes standard, and the advanced driver-assistance systems can be adjusted through MBUX for sensitivity and alerts. The suite includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centering assist, with especially smooth operation in real-world driving.
• Infotainment: The GLS uses dual 12.3-inch displays, including a digital instrument panel and infotainment touchscreen. MBUX includes improved graphics, intuitive touchscreen operation, natural voice recognition, augmented reality navigation, and wireless-style convenience through its modern interface, though touch-sensitive controls can be distracting.
• Fuel efficiency: The GLS 450 is rated at 21 mpg in combined driving.

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 luxury, technology, and comfort that define the model.
• GLS 580: This is the step-up choice if you want more power and a more upscale feel than the GLS 450, and it is also the model tied to the available Off-Road Package. That package adds underbody protection, up to 1.2 inches of extra ground clearance, and improved water fording capability.
• AMG GLS 63: This is the performance-oriented choice in the lineup, aimed at buyers who want the most aggressive version of the GLS model series.
• Maybach GLS 600: This is the most luxurious choice if your priority is maximum exclusivity and the highest-end presentation in the range.

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

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 with some leverage if you stay disciplined.

• Deal availability: 37.2% of listings are priced as good or great deals.
• Inventory: There are 1,421 listings available.
• Price trend: Prices have softened 11.72% compared with last year.
• Clean inventory: 93.5% of listings are accident-free.

If you find a listing below $72,504, 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 $72,504 sits slightly below last year's $82,132.

That price movement suggests the market has cooled, which can help you as a buyer now but may also mean a future seller has less room to recover prior pricing. If you buy at the right number and keep the vehicle in strong condition, you can reduce the impact of that softer market.

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 you can adjust 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 describes their operation as subtle, smooth, and transparent.

One caveat is that the lane-centering assist briefly turned off in a specific low-speed intersection scenario during evaluation, so you should still stay attentive even with the systems engaged.

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:

• 37.2% 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 11.72% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2024 model brings minor styling modifications, fresh colors and trim, more standard equipment, enhanced off-roading technology, and a new version of MBUX.

The bottom line: If you want the freshest version of this three-row luxury SUV, the 2024 is the right place to start because it adds useful updates without changing the GLS’s core strengths. If your main goal is to minimize purchase price, a nearby model year may be worth comparing, but the 2024’s softer pricing and strong inventory make it a compelling target for shoppers who want the updated package.
