Is the 2023 Mercedes-Benz GLS a good car?

The 2023 Mercedes-Benz GLS is aimed at families that want the comfort and space of a luxury sedan with some off-road capability, and it delivers that with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. It also stands out for premium interior materials and easy-to-use technology, while the roomy cabin and upscale feel make it a strong fit if you want a large luxury SUV that still feels refined.

For 2023, the GLS450 gained a panoramic moonroof and metallic paint as standard equipment, and the model year includes dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, wireless charging, and power-folding third-row seats. The overall package is especially appealing if you value comfort, space, and a broad mix of convenience features.

32.3% of listings are priced as good or great deals, which gives you a meaningful share of market opportunities to compare.

Is the 2023 Mercedes-Benz GLS reliable?

The 2023 Mercedes-Benz GLS is described as comfortable, upscale, and well equipped, with easy-to-use technology among its strengths. It also benefits from a broad mix of standard convenience and safety features that support everyday use.

For used buyers, long-term ownership risk is tied more to the complexity of a large luxury SUV than to any single feature, so condition and maintenance history matter a lot.

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

Accident-free inventory is excellent at 91.6% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially on a luxury SUV with lots of technology and power equipment. Focus on the condition of the third row, seat mechanisms, infotainment functions, and any signs of wear that could hint at heavy family use.

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

This looks like a moderate, selective buyer’s market, so you have room to shop carefully without expecting every listing to be a bargain.

• Deal availability: 32.3% of listings are priced as good or great deals.
• Inventory: There are 1,212 listings available.
• Price trend: Prices have softened 8.48% compared with last year.
• Clean inventory: 91.6% of listings are accident-free.

If you find a listing below $65,202, 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 $65,269 sits slightly below last year's $71,319.

That price movement suggests the market has cooled, which can help you buy more confidently today. For a future seller, it also means resale value may depend heavily on mileage, condition, and how well the vehicle is equipped and maintained. If you buy well now and keep the SUV in strong shape, you may be better positioned when it is time to sell.

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

Consider the 2024 if:

• At $72,725, the 2024 costs more than the current year's $65,269 average.
