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 also positioned as a midsize SUV that blends the comfort and space of the S-Class luxury sedan with a modicum of off-road capability from the G-Class. That combination gives it a clear identity: it is a large, family-focused luxury SUV that still carries Mercedes-Benz’s emphasis on refinement.

For 2023, the GLS450 gained a panoramic moonroof and metallic paint as standard equipment. The broader second-generation GLS also brought a more curvy exterior design and a wide-screened, tech-forward cabin, along with more comfort and safety features. Standard equipment included dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, SiriusXM, nine USB-C ports, wireless charging, heated front seats, MB-Tex upholstery, a sunroof, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels.

The 2023 GLS is appealing because it delivers a lot of luxury and practicality in one package, and the available seating flexibility is especially useful for families. At the same time, it is not without compromises: the second-generation GLS lost some cargo space compared with the previous version, and the buying guide notes that third-row seat access and touch-sensing controls are drawbacks. Even so, its combination of space, comfort, and standard technology makes it a distinctive choice among three-row luxury SUVs.

29.2% of listings are priced as good or great deals, so you have a meaningful but selective set of opportunities.

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 if prior maintenance was inconsistent.

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

Accident-free inventory is excellent at 90.5% — clean inventory, standard diligence applies.

You should still run a vehicle history report to confirm the listing’s background and look for any prior damage or title issues. Prioritize a thorough inspection of the third-row access, touch-sensing controls, and overall cabin wear, since those are the kinds of areas that can affect day-to-day satisfaction. Because this is a luxury SUV with a lot of equipment, condition and maintenance history matter as much as mileage.

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

The current average of $65,599 sits slightly below last year's $72,461.

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 condition, mileage, and how well the vehicle has been maintained. Well-kept examples should still hold appeal because the GLS remains a high-demand luxury SUV with strong family utility.

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