The 2026 Mercedes-Benz GLS sits at a median of $108,800 in the Canadian market right now. Most examples land between $101,822 and $134,948, which is a wide spread of roughly $33,000. That gap tells you configuration and condition are doing real work on price, so where a given GLS falls in that band matters more than the median alone.
Median distance on these is 18,900 km. That's low, and it should be for a 2026. Anything you find near that number is barely broken in, so a big odometer reading on a car this new is worth a second look and a harder negotiation.
What mileage does to the price
Distance moves the number fast here. Every 10,000 km knocks about $14,413 off the price. On a car most people are buying with under 20,000 km on the clock, that's a steep curve. A GLS sitting at 40,000 km instead of the typical 18,900 is worth roughly $30,000 less on mileage alone, before you even look at trim or condition.
Run the math before you commit. If a lower-mileage example is priced a few thousand above one with 20,000 extra km, the low-km car is usually the better buy once you weigh that $14,413-per-10,000 hit.
