How much does the 2023 Mercedes-Benz GLS cost?

Prices have softened 22.61% compared to this time last year, making it a favourable time to shop this model year.

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 2,400 litres of cargo space. For you, that means it is built around space, luxury, and everyday usability, especially if you want a large upscale SUV without moving to something more specialised.

It also brings a wide-screened, tech-forward cabin with dual 12.3-inch displays, MBUX infotainment, navigation, a Burmester surround sound stereo, SiriusXM, nine USB-C ports, wireless charging, and three years of Mercedes Me Connect services. Standard equipment includes heated front seats, MB-Tex upholstery, a sunroof, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels.

For shoppers who value a polished feel and generous standard equipment, the GLS makes a strong case. 32.7% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2023 Mercedes-Benz GLS reliable?

The 2023 Mercedes-Benz GLS is presented as a comfort-focused, premium SUV with easy-to-use technology and a generous equipment list. Its appeal comes from the way it combines luxury, space, and everyday usability in one package.

The main trade-offs are third-row access and touch-sensing controls, which can affect day-to-day convenience. For long-term ownership, those practical compromises matter most if you plan to use the third row often or want the simplest possible cabin experience.

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

This looks like a moderate, selective buyer’s market, so you can afford to be patient and compare listings carefully.

• Deal availability: 32.7% of listings are priced as good or great deals.
• Inventory: There are 55 listings available.
• Price trend: Prices have softened 22.61% compared with last year.

If you find a listing below $99,393 CAD, 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 $112,070 CAD sits slightly below last year's $144,805 CAD.

That price movement suggests the market has cooled, which can make the GLS more attractive to used buyers today. If you buy at the current average or below, you may have less downside risk than someone who bought when prices were higher.

For a future seller, the softer market means resale value may depend more heavily on condition, mileage, and equipment. A well-kept GLS with desirable features should still stand out, but you should not expect the same pricing strength seen a year ago.

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:

• 32.7% of listings are priced as good or great deals.
• Price trend: Prices have softened 22.61% compared with last year.

Consider the 2022 if:

• At $68,541 CAD, the 2022 costs less than the current year's $112,070 CAD average.
• It offers a clearly defined, prestige-focused three-row luxury SUV choice.

Consider the 2024 if:

• At $92,979 CAD, the 2024 costs less than the current year's $112,070 CAD average.
• It adds refreshed styling, more standard equipment, and updated infotainment.

The bottom line: The 2023 is the best fit if you want the current-year GLS experience with a meaningful price correction already reflected in the market. If you are more price-sensitive, the 2022 is the value play, while the 2024 is the better choice if you want newer updates without paying the current-year average.
