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 an S-Class luxury sedan with some off-road capability. It 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.

Its standard equipment is generous, including dual 12.3-inch displays with MBUX touchscreen functionality, navigation, a Burmester surround sound stereo, wireless charging, nine USB-C ports, heated front seats, MB-Tex upholstery, a sunroof, and power-folding third-row seats. For shoppers who want a large luxury SUV with strong comfort, space, and technology, it fits the brief well.

26.2% 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- and convenience-focused luxury SUV with strong standard safety and convenience content. Its cabin and equipment list suggest a well-appointed ownership experience, especially if you value space and technology.

At the same time, the touch-sensing controls and third-row access remain drawbacks, so long-term ownership risk for used buyers is more about living with the SUV’s usability quirks than about its core mission.

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

This is a moderate buyer’s market, so you can be selective without expecting every listing to be a bargain.

• Deal availability: 26.2% of listings are priced as good or great deals.
• Inventory: There are 61 listings available.
• Price trend: Prices have softened 21.03% 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 $99,884 CAD sits slightly below last year's $126,485 CAD.

That drop suggests the market has moved in buyers’ favour, which can make the GLS easier to purchase now than it was a year ago. For a future seller, though, it also means you may face more pressure on resale if pricing softens further. If you buy carefully today, you can reduce the risk of overpaying and improve your odds of holding value reasonably well.

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:

• 26.2% of listings are priced as good or great deals.
• Price trend: Prices have softened 21.03% compared with last year.

Consider the 2022 if:

• At $67,877 CAD, the 2022 costs less than the current year's $99,884 CAD average.
• It remains the current-generation flagship with maximum space and status.

Consider the 2024 if:

• At $96,984 CAD, the 2024 costs less than the current year's $99,884 CAD average.
• It adds refreshed styling, more standard equipment, and updated infotainment.

The bottom line: The 2023 makes sense if you want the strongest mix of current pricing, inventory, and a well-equipped three-row luxury SUV. If you are more price-sensitive, the 2022 is the better value play, while the 2024 is the smarter choice if you want the newer updates without paying much more.
