How much does the 2023 Mercedes-Benz GLS cost?

Prices have softened 10.74% compared to this time last year, making it a favorable time to shop this model year.

With 1,268 listings available, you have a solid amount of inventory to compare across trims and conditions.

If you find a listing below $65,588.13, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2023 Mercedes-Benz GLS a good car?

The 2023 Mercedes-Benz GLS stands out as the roomiest vehicle in the Mercedes-Benz lineup, with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. It is also positioned as a midsize SUV that blends the comfort and space of the S-Class luxury sedan with a modicum of off-road capability from the G-Class.

That combination gives it a clear identity: it is a large, family-focused luxury SUV that still carries Mercedes-Benz’s emphasis on refinement. For 2023, the GLS450 gained a panoramic moonroof and metallic paint as standard equipment, and the broader second-generation GLS brought a wide-screened, tech-forward cabin along with more comfort and safety features.

The model is appealing because it delivers a lot of luxury and practicality in one package, and the available seating flexibility is especially useful for families. 33.8% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2023 Mercedes-Benz GLS reliable?

The 2023 Mercedes-Benz GLS is presented as a refined, family-focused luxury SUV with a strong emphasis on comfort, space, and standard technology. Its 48-volt mild hybrid system was designed to reduce fuel consumption, enable faster and smoother engine restarts, and provide electric torque from a standstill.

The model also benefits from a broad set of standard equipment, including dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, wireless charging, heated front seats, and power-folding third-row seats. Those features suggest a well-equipped ownership experience, but the GLS’s size and complexity mean long-term ownership risk can rise if you skip careful maintenance and inspection.

What should I look for when buying a used 2023 Mercedes-Benz GLS?

Accident-free inventory is excellent at 90.4% — clean inventory, standard diligence applies.

You should still run a vehicle history report and verify that the specific SUV you’re considering has a clean title and consistent service records. Prioritize a pre-purchase inspection, especially for the third row, touch-sensitive controls, and any signs of wear in a large family vehicle that may have seen heavy use.

Focus on overall condition, because a luxury SUV with this much equipment can be expensive to refresh if previous owners deferred maintenance or used it hard.

Is now a good time to buy a used 2023 Mercedes-Benz GLS?

What is the 2023 Mercedes-Benz GLS's resale value?

The current average of $65,593 sits slightly below last year's $73,485.

That price movement suggests the GLS has already absorbed a meaningful amount of depreciation, which can help you if you buy now and hold it for a while. For a future seller, the current market is a reminder that luxury SUVs can lose value quickly when newer model years arrive with fresh equipment and updates.

If you plan to sell later, the best protection is to buy a clean, well-kept example and keep mileage and condition in check. A strong service history and accident-free record should help you preserve more of the remaining value.

Should I buy a 2023 Mercedes-Benz GLS or consider a different year?

If you're weighing the 2023 against nearby model years, here's how to think about it:

Choose the 2023 if:

• 33.8% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 90.4% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 10.74% compared with last year.

Consider the 2022 if:

• At $48,712, the 2022 costs less than the current year's $65,593 average.
• It is a simpler, less upscale version with a more basic feature set.

Consider the 2024 if:

• At $72,856, the 2024 costs more than the current year's $65,593 average.
• It adds fresher styling and updated tech.

The bottom line: The 2023 is the best all-around choice if you want a roomy, well-equipped luxury SUV and can take advantage of the softer pricing. If your priority is saving money, the 2022 is the better value path; if you want the newest updates and can stretch your budget, the 2024 is the upgrade route.
