How much does the 2024 Mercedes-Benz GLS cost?

Prices have softened 11.82% compared to this time last year, making it a favorable time to shop this model year.

There are 1,441 listings available, which suggests healthy inventory for a luxury SUV at this price point.

If you find a listing below $72,803.15, 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 stands out as a large three-row luxury SUV that emphasizes upscale comfort, premium interior materials, and easy-to-use technology, while the 2024 updates add fresh styling touches, more standard equipment, enhanced off-roading technology, and a new MBUX system. The main trade-offs are that the AMG Line Package can make entry and exit harder, third-row access is a challenge, and touch-sensitive controls may not suit everyone.

The GLS 450’s straight-six powertrain is described as smooth and lively, while the larger V8-powered versions are available if you want more output. The expert take also notes that the GLS is especially appealing if you want a luxury SUV that does many things well rather than excelling at only one task.

29.5% 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 2024 GLS is presented as a refined, well-rounded luxury SUV that builds on an already appealing formula with updated styling, more standard equipment, and a new infotainment system. Its powertrain is described as smooth, quiet, and well calibrated, and the mild-hybrid setup adds instant torque off the line. The expert evaluation also emphasizes that the GLS won’t fail to meet expectations, which is a useful sign for used buyers looking for a premium vehicle that should feel solid in daily use.

Mercedes also highlights the GLS’s efficiency-minded mild-hybrid system, which helps reduce fuel consumption and supports smoother engine restarts. For used buyers, the main long-term ownership risk is less about core durability and more about living with a complex, high-end SUV whose advanced features and luxury hardware can be costly if they need attention.

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

Accident-free inventory is excellent at 92.9% — 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 driver-assistance systems. Pay close attention to how the touch-sensitive controls behave, whether the third row is usable for your needs, 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 more accessible pricing and strong equipment make it the best-value starting point if you want the core GLS experience without paying for extra power.
• Powertrain: The GLS 450 uses a turbocharged 3.0-liter inline six-cylinder engine with mild-hybrid technology, while the higher versions use a twin-turbo V8 with mild-hybrid assistance. The GLS 450 is described as smooth, quick, and efficient enough that you may not need the extra power or added ownership cost of the V8 models.
• Infotainment: The GLS uses a 12.3-inch digital instrument panel and a 12.3-inch infotainment touchscreen, with improved graphics, intuitive touchscreen operation, natural voice recognition, and augmented reality navigation. Touch-sensitive controls on the steering wheel and center console can be distracting, so make sure they work the way you expect.
• 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 most affordable way into the GLS lineup, and it delivers the core strengths of the model: smooth performance, strong efficiency, premium materials, and easy-to-use technology. If you want the best value, this is the trim to start with.
• GLS 580: This trim moves you up to the twin-turbo V8 setup and is the one explicitly tied to the available 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 hardware mentioned here.
• AMG GLS 63: This is the performance-focused step in the lineup, aimed at buyers who want the more powerful V8 character and a more aggressive version of the GLS experience.
• Maybach GLS 600: This is the top luxury choice for buyers who want the most upscale expression of the GLS nameplate and are willing to pay for it.

Safety comes standard on the 2024 GLS, and the expert evaluation says it includes 20+ significant safety features.

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 carefully without expecting every listing to be a bargain.

• Deal availability: 29.5% of listings are priced as good or great deals.
• Inventory: There are 1,441 listings available.
• Price trend: Prices have softened 11.82% compared with last year.
• Clean inventory: 92.9% of listings are accident-free.

If you find a listing below $72,803.15, 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 $72,877 sits slightly below last year's $82,646.

That price movement suggests the market has already adjusted downward, which can help you buy more confidently now but may also mean less immediate upside if you plan to resell soon. For a future seller, the key takeaway is that the GLS’s value is being supported by strong luxury-SUV demand, but the current softer pricing means you should buy with a realistic view of depreciation. Well-equipped examples in strong condition should still be 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?

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

Safety comes standard on the 2024 GLS, and the expert evaluation highlights a broad set of advanced driver-assistance systems that you can customize through MBUX. The suite includes forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and lane-centering assist, and the expert notes that these systems operate smoothly and transparently in real-world driving.

The only caveat called out is that lane-centering assist briefly turned off once during evaluation on a tricky road segment, though it otherwise handled varied roads without trouble. Overall, the GLS’s safety tech is presented as a major strength, and the standard equipment list is substantial.

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:

• 29.5% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 92.9% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 11.82% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• This year brings minor styling updates, more standard equipment, enhanced off-roading technology, and a new MBUX infotainment system.

The bottom line: The 2024 GLS is the right pick if you want the freshest version of this luxury SUV with updated tech and a softer market than last year. If your priority is simply getting into a GLS for less money, a nearby older year may be worth a look, but the 2024 gives you the most current mix of comfort, technology, and safety.
