Is the 2023 Mercedes-Benz GLS a good car?

The 2023 Mercedes-Benz GLS is 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 designed as a large, family-focused luxury SUV that blends Mercedes-Benz comfort and refinement with a bit of off-road capability, and it brings a wide-screen, tech-forward cabin with a long list of standard equipment.

That makes it a strong fit if you want a luxury SUV that prioritizes space, comfort, and everyday usefulness. The combination of seating flexibility and standard technology is especially appealing for families who need a premium three-row vehicle.

34.3% of listings are priced as good or great deals, which gives you a meaningful share of the market to target.

Is the 2023 Mercedes-Benz GLS reliable?

The 2023 Mercedes-Benz GLS is presented as a refined, comfort-oriented luxury SUV with a strong emphasis on standard technology and family usability. Its 48-volt mild hybrid system is aimed at smoother engine restarts and improved fuel consumption, and the model’s overall setup is built around premium daily driving.

For used buyers, the main long-term ownership risk is that a large, highly equipped luxury SUV can be expensive to keep in top condition, so maintenance history matters.

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

Accident-free inventory is excellent at 90.7% — clean inventory, standard diligence applies.

You should still run a history report and verify that the vehicle’s condition matches the listing photos and description. Prioritize a pre-purchase inspection, especially if you are considering a higher-mileage example or one with signs of heavy family use. Pay close attention to interior wear, third-row operation, and any issues with the controls or electronics.

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

The current average of $65,229 sits slightly below last year's $71,995.

That price movement suggests the market has already adjusted downward, which can help you buy more confidently today.

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:

• 34.3% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 90.7% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 9.40% compared with last year.

Consider the 2022 if:

• At $48,156, the 2022 costs less than the current year's $65,229 average.
• The prior year is a more stripped-back, value-focused flagship SUV.

Consider the 2024 if:

• At $72,824, the 2024 costs more than the current year's $65,229 average.
• The refreshed model adds updated styling, more standard equipment, and newer infotainment.

The bottom line: The 2023 is the best all-around path if you want a strong mix of space, luxury, and market value. If your priority is lower purchase price, the 2022 is the better budget-conscious alternative. If you want the newer refresh and are willing to pay more, the 2024 is the upgrade to consider.
