Used 2024 Mercedes-Benz GLS for Sale nearMilwaukee, WI

How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 15.01% compared to this time last year, making it a favorable time to shop this model year.

There are 1,517 listings available, which suggests you have 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 describes it as a large three-row luxury SUV that has been refreshed with minor styling changes, fresh colors and trim, more standard equipment, enhanced off-roading technology, and a new version of its MBUX infotainment system. That combination keeps it current while preserving the core appeal of a comfortable, premium, tech-forward SUV.

The main trade-offs are that the AMG Line Package can impede entry and exit, third-row seat access is a limitation, and the touch-sensing controls may not suit everyone. Even so, it fits well if you want a high-end family SUV that emphasizes comfort and technology over sheer utility.

37.6% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2024 Mercedes-Benz GLS reliable?

The overview points to a refined, well-rounded luxury SUV, and the expert evaluation reinforces that impression with praise for its comfort, technology, and overall day-to-day livability. The performance notes also describe the GLS 450 as smooth, silky, quick, and quiet, with a powertrain that feels lively from a stop thanks to its mild-hybrid assist.

The cost-effectiveness commentary adds that the GLS 450 combines likable looks, superb comfort, class-leading technology, rewarding driving dynamics, and impressive efficiency. For used buyers, the main long-term ownership risk is less about basic competence and more about whether you’re comfortable with the complexity and cost that come with a large, highly equipped luxury SUV.

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

Accident-free inventory is excellent at 91.7% — 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 a long list of standard features. Pay close attention to cabin condition, seat access and operation, and whether the controls and driver-assistance systems behave the way you expect during a test drive.

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 up in equipment and power. The GLS 450’s cabin 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.
• Powertrain: The GLS 450 uses a turbocharged 3.0-liter inline six-cylinder engine with mild-hybrid technology. It delivers 375 horsepower and 369 pound-feet of torque, and the mild-hybrid system adds an instant 148 lb-ft of torque when you accelerate.
• Safety package: Safety comes standard, and the GLS includes 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. The text also notes that the GLS offers more than 20 significant safety features.
• Infotainment: The GLS uses a 12.3-inch digital instrumentation panel and a 12.3-inch infotainment touchscreen. MBUX includes improved graphics, Classic, Sporty, and Discreet themes, plus Navigation, Assistance, and Service modes. It also offers intuitive touchscreen operation, natural voice recognition, and augmented reality for navigation.
• Fuel efficiency: The official fuel economy rating is 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 because it delivers the core GLS experience: smooth power, strong comfort, and the latest MBUX system without pushing you into the higher-cost V8 models. It’s the trim that best matches the model’s balance of luxury, technology, and efficiency.
• GLS 580: This step up is for you if you want the twin-turbo V8 with MHEV and the added capability of the available Off-Road Package, which includes underbody protection, up to 1.2 inches of added ground clearance, and improved water fording capability.
• AMG GLS 63: Choose this if you want the AMG-tuned version of the GLS lineup and are shopping for the most performance-focused model explicitly named in the data.
• Maybach GLS 600: This is the top luxury-oriented choice in the lineup if you want the most exclusive version explicitly mentioned.

Safety comes standard across the GLS lineup, and the available driver-assistance systems are a major part of the appeal.

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 patiently but should move quickly on strong listings.

• Deal availability: 37.6% of listings are priced as good or great deals.
• Inventory: There are 1,517 listings available.
• Price trend: Prices have softened 15.01% compared with last year.
• Clean inventory: 91.7% of listings are accident-free.

If you find a listing below $68,566, 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 $68,566 sits slightly below last year's $80,676.

That price decline suggests the market has already adjusted downward, which can help you buy at a more favorable point in the cycle. For a future seller, that also means resale value will depend heavily on condition, mileage, and how well the vehicle is equipped.

Because the GLS sits in the luxury SUV segment, well-kept examples with desirable equipment should remain easier to move than neglected ones. 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 from IIHS and five-star ratings from NHTSA.

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

Safety comes standard on the 2024 Mercedes-Benz GLS, and the driver-assistance systems can be adjusted through MBUX so you can tailor sensitivity and alerts to your preference. The system includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centering assist.

The evaluation also notes that the GLS handled challenging roads without trouble and that the ADAS operated transparently without causing driver aggravation. One caveat is that lane-centering assist momentarily turned off once during the test route.

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:

• 37.6% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 91.7% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 15.01% compared with last year.

The bottom line: The 2024 GLS is the right pick if you want the refreshed version with updated styling and technology while still shopping in a market where prices have eased. If you’re especially price-sensitive, a nearby model year may be worth comparing, but the 2024 stands out as the more current and well-equipped choice.
