Used 2024 Mercedes-Benz GLS for Sale near Pennsylvania

How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 11.62% compared to this time last year, making it a favorable time to shop this model year.

There are 1,448 listings available, which gives you a solid amount of inventory to compare across trims and condition levels.

If you find a listing below $72,622.54, that's toward the low end of the year-round range and worth acting on quickly.

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 comes across as a large three-row luxury SUV that emphasizes upscale comfort, premium interior materials, and easy-to-use technology, while still feeling current thanks to its refreshed styling, updated trim, and newer infotainment system. The main trade-offs are that the price of entry is steep, the AMG Line Package can make entry and exit more awkward, third-row access is a challenge, and touch-sensitive controls may frustrate you.

For shoppers who want a refined family hauler with a luxury-first personality, that mix makes sense. The market also shows 33.9% 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 2024 GLS is presented as a well-rounded luxury SUV that builds on an already appealing formula, with comfort, premium materials, and technology that are meant to make daily use feel effortless. Its powertrain is described as smooth, quiet, and well calibrated, and the mild-hybrid setup adds instant torque off the line for a more responsive feel.

Mercedes also positions the GLS as a vehicle that can do a lot well instead of excelling at only one task, which supports the idea of broad everyday dependability. The first scheduled maintenance visit is on the house, which helps soften early ownership costs.

For used buyers, the main long-term risk is less about outright durability and more about whether the vehicle’s complex luxury features and touch-sensitive controls have been cared for properly.

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

Accident-free inventory is excellent at 93.2% — clean inventory, standard diligence applies.

You should still run a history report and prioritize a pre-purchase inspection, especially on a luxury SUV with a lot of standard technology and driver-assistance equipment. Pay close attention to how the interior controls, seating access, and electronic systems feel in real 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 uses a turbocharged 3.0-liter inline six-cylinder engine with mild-hybrid technology, while the GLS 580, AMG GLS 63, and Maybach GLS 600 move to a twin-turbo V8 with mild-hybrid support. The GLS 450 is the value play if you want the core luxury experience without paying for extra power you may not need.
• Powertrain: The GLS 450 delivers 375 horsepower and 369 pound-feet of torque, with a nine-speed automatic and all-wheel drive. It is described as smooth, silky, and quick enough for most buyers, while the mild-hybrid system adds an instant 148 lb-ft of torque when you accelerate.
• Safety package: Safety comes standard, and the suite includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centering assist. You can adjust many of these systems through the infotainment system, which helps you tailor how intrusive they feel.
• Infotainment: The GLS uses a pair of 12.3-inch displays with the latest MBUX system, improved graphics, and helpful navigation, assistance, and service modes. It also includes augmented reality navigation and a standard Burmester surround-sound system with Dolby Atmos technology.
• 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 with the turbocharged inline-six, strong performance, and the same upscale comfort and technology that define the model. If you want the most balanced version, start here.
• GLS 580: This trim steps up to the twin-turbo V8 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-focused hardware mentioned here.
• AMG GLS 63: This is the performance-oriented step-up for buyers who want the AMG-branded version of the GLS experience and are willing to pay for it.
• Maybach GLS 600: This is the most luxurious version in the lineup and suits you if you want the most exclusive, comfort-focused interpretation of the GLS.

Safety comes standard across the lineup, so you do not need to move up a trim just to get the core driver-assistance coverage.

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

The market looks moderate and selective, so you can shop with patience but should move quickly on the right example.

• Deal availability: 33.9% of listings are priced as good or great deals.
• Inventory: There are 1,448 listings available.
• Price trend: Prices have softened 11.62% compared with last year.
• Clean inventory: 93.2% of listings are accident-free.

If you find a listing below $72,622.54, 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 $72,824 sits slightly below last year's $82,400.

That price movement suggests the market has already adjusted downward, which can help you as a buyer today but may also mean a future seller has less cushion if prices keep easing. If you buy well and keep the vehicle in strong condition, you may be better positioned than someone who pays closer to the top of the range.

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?

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

Safety comes standard on the 2024 Mercedes-Benz GLS, and the driver-assistance suite is extensive. It includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centering assist, and you can adjust many of those systems through the infotainment menu to better suit your preferences.

The system is described as smooth and transparent in real-world use, with subtle steering and speed adjustments that avoid unnecessary driver aggravation. One caveat is that lane-centering assist briefly turned off in one specific situation during evaluation, so you should still stay engaged behind the wheel.

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:

• 33.9% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 93.2% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 11.62% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• This year brings refreshed styling, more standard equipment, enhanced off-roading technology, and an updated MBUX system.

The bottom line: If you want the freshest version of the GLS with updated tech and a softer market than last year, the 2024 is the one to target. If your priority is simply getting into a GLS for less money, a nearby model year may be worth comparing, but the 2024 gives you the most current mix of luxury, technology, and refinement in this range.
