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 positioned as a full-size SUV that blends the comfort and space of the S-Class luxury sedan with some off-road capability, which helps explain why it feels more like a family-focused luxury hauler than a traditional truck-based SUV.

For buyers who want a large luxury SUV with strong space, a polished cabin, and a long list of comfort and convenience features, the 2023 Mercedes-Benz GLS remains an appealing choice. The market also shows 38.2% of listings as good or great deals, which suggests there are worthwhile opportunities if you shop carefully.

Is the 2023 Mercedes-Benz GLS reliable?

The 2023 Mercedes-Benz GLS is presented as a large luxury SUV with a polished cabin, practical convenience features, and a strong focus on comfort and versatility. Its wide-screened, tech-forward interior and easy-to-live-with seating and cargo flexibility support that everyday usability.

For long-term ownership, you should still budget for the realities of a large premium SUV, where maintenance and repair costs can be higher than average if wear items or electronics need attention.

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

Accident-free inventory is solid at 89.8% — always verify the vehicle history report.

You should prioritize a history report first, then inspect the SUV closely for signs of prior damage, uneven wear, or neglected maintenance. Pay special attention to the third row, seat-folding functions, and cabin features so you know the vehicle’s convenience systems are working as expected.

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

This is a moderate market for selective buyers, so you can shop with some leverage if you focus on the right listings.

• Deal availability: 38.2% of listings are priced as good or great deals.
• Inventory: There are 1,367 listings available.
• Price trend: Prices have softened 11.62% compared with last year.
• Clean inventory: 89.8% of listings are accident-free.

If you find a listing below $62,294, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $62,294 sits slightly below last year's $70,484.

That price movement suggests the market has cooled, which can help you buy more affordably today. 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 should be in a stronger position when it is time to sell.

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:

• 38.2% of listings are priced as good or great deals.
• Accident-free inventory is solid at 89.8% — always verify the vehicle history report.
• Price trend: Prices have softened 11.62% compared with last year.

Consider the 2022 if:

• At $45,466, the 2022 costs less than the current year's $62,294 average.
• It offers a flagship three-row layout with strong presence.

Consider the 2024 if:

• At $68,566, the 2024 costs more than the current year's $62,294 average.
• It adds refreshed styling and updated tech.

The bottom line: If you want the best balance of price, inventory, and deal potential, the 2023 is the primary path to consider. If your budget is tighter, the 2022 is the better secondary option because it undercuts the current-year average by a wide margin.
