Used 2025 Mercedes-Benz GLS for Sale near Illinois

How much does the 2025 Mercedes-Benz GLS cost?

Prices have softened 11.02% compared to this time last year, making it a favorable time to shop this model year.

There are 1,480 listings available, which suggests you have a meaningful amount of inventory to compare.

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. It is aimed at buyers who want a large Mercedes with genuine passenger and cargo flexibility, and it blends the comfort and space of the S-Class luxury sedan with some off-road capability.

That combination makes it especially appealing if you want a family-focused luxury hauler rather than a traditional SUV. The standard equipment list is also substantial, with dual 12.3-inch displays, MBUX, navigation, a Burmester surround sound stereo, wireless charging, power-folding third-row seats, and power-adjustable second-row seats.

36.8% of listings are priced as good or great deals, which gives you a decent chance to find a competitive offer.

Is the 2025 Mercedes-Benz GLS reliable?

The 2025 Mercedes-Benz GLS is presented as a comfort- and safety-focused luxury SUV with a long list of standard features, which supports its appeal for buyers who want a premium three-row vehicle. It also benefits from the second generation’s emphasis on added comfort and safety features.

For used buyers, the main long-term ownership risk is that a large, highly equipped luxury SUV can be costly to keep in top condition over time.

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

Accident-free inventory is excellent at 96% — clean inventory, standard diligence applies.

You should still run a history report on any listing you’re seriously considering, especially if the vehicle has had multiple owners or a complex service history. Prioritize a pre-purchase inspection that focuses on the third-row access mechanisms, touch controls, and overall cabin condition, since those are the areas most likely to affect day-to-day satisfaction.

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

This looks like a moderate, selective buyer’s market, so you can shop patiently and still expect some room to negotiate.

• Deal availability: 36.8% of listings are priced as good or great deals.
• Inventory: There are 1,480 listings available.
• Price trend: Prices have softened 11.02% compared with last year.
• Clean inventory: 96.0% of listings are accident-free.

If you find a listing below $79,394, 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 $79,907 sits slightly below last year's $89,800.

That price movement suggests the market has already adjusted downward, which can help you buy with less risk of overpaying. For a future seller, it also means resale value may depend heavily on condition, mileage, and how well the vehicle is equipped and maintained. If you keep the SUV clean, documented, and accident-free, you’ll be in a stronger position when it’s time to trade or sell.

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:

• 36.8% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 96% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 11.02% compared with last year.

Consider the 2024 if:

• At $72,504, the 2024 costs less than the current year's $79,907 average.
• It adds a refreshed look and updated tech.

Consider the 2026 if:

• It offers more passenger room and cargo space than any other Mercedes SUV.

The bottom line:

The 2025 is the best all-around pick if you want the current-year balance of price, inventory, and feature content. If your priority is stretching your budget, the 2024 is the smarter secondary path because it delivers a lower entry price while keeping much of the GLS formula intact.
