How much does the 2025 Mercedes-Benz GLS cost?

Is the 2025 Mercedes-Benz GLS a good car?

The 2025 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. That makes it a strong fit for you if you want full-size family utility without giving up the brand’s emphasis on comfort and luxury.

It also blends the comfort and space of the S-Class luxury sedan with a modicum of off-road capability from the G-Class, which helps explain its broad appeal. Standard equipment includes dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, SiriusXM, nine USB-C ports, wireless charging, three years of Mercedes Me Connect services, heated front seats, MB-Tex upholstery, a sunroof, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels.

33.2% of listings are priced as good or great deals, which gives you a meaningful share of the market to shop from.

Is the 2025 Mercedes-Benz GLS reliable?

The 2025 Mercedes-Benz GLS is presented as a spacious, upscale three-row SUV with a strong mix of comfort, technology, and everyday usefulness. Its emphasis on convenience and standard equipment suggests a well-rounded ownership experience for buyers who value refinement.

The tradeoffs are practical rather than mechanical: third-row access and touch-sensing controls are drawbacks, so you should expect some usability compromises in daily use. For long-term ownership, that means your biggest risk is likely to come from complexity and wear in a large luxury SUV rather than from a simple, low-cost ownership profile.

What should I look for when buying a used 2025 Mercedes-Benz GLS?

Accident-free inventory is excellent at 95.6% — clean inventory, standard diligence applies.

You should still run a vehicle history report and verify that the listing matches the seller’s claims on mileage, ownership, and service records. Prioritize a pre-purchase inspection that focuses on the third row, seat mechanisms, electronics, and any signs of interior wear, since those are the areas most likely to matter in a large luxury SUV.

Is now a good time to buy a used 2025 Mercedes-Benz GLS?

This looks like a moderate, selective buyer’s market, so you have room to shop carefully and compare listings.

• Inventory: There are 1,504 listings available.
• Price trend: Prices have softened 12.26% compared with last year.

If you find a listing below $79,465.06, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2025 Mercedes-Benz GLS's resale value?

The current average of $79,629 sits slightly below last year's $90,754.

That price movement suggests the market has already adjusted downward, which can help you buy with less risk of immediate overpayment. If you plan to sell later, the current softness means your resale outcome will depend heavily on mileage, condition, and how well the vehicle is equipped.

For you as a future seller, the best protection is to buy a clean example now and keep it in strong condition. A well-maintained GLS with desirable equipment should hold up better than one with visible wear or a rough history.

Should I buy a 2025 Mercedes-Benz GLS or consider a different year?

If you're weighing the 2025 against nearby model years, here's how to think about it:

Choose the 2025 if:

• 33.2% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 95.6% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 12.26% compared with last year.

Consider the 2024 if:

• At $72,824, the 2024 costs less than the current year's $79,629 average.
• It adds refreshed styling, more standard equipment, and updated infotainment.

Consider the 2026 if:

• It offers more passenger room and cargo space than any other Mercedes SUV.
• It emphasizes comfort, refinement, and rewarding driving dynamics.

The bottom line: You should start with the 2025 if you want the best balance of current pricing, strong inventory quality, and broad family usefulness. If your priority is saving money, the 2024 is the better secondary path because it delivers many of the same core strengths at a lower average price.
