The median 2020 Mercedes-Benz GLB in the Canadian market sits at $26,395. Most of what you'll run into lands between $24,910 and $28,498. That's a tight spread, only about $3,600 wide, which tells you the market has settled on what this year is worth. A price outside that band is worth a second look, either as a bargain or a warning sign.
Median mileage on these is right around 85,000 km. So when you see the $26,395 figure, picture a GLB with roughly that much on the clock. A car with far less should sit near the top of the range or above it, and one pushing well past 85,000 should come in below the median.
What mileage does to the price
Every extra 10,000 km knocks about $673 off. Put that in real terms. A GLB at 65,000 km carries roughly $1,350 more value than the median example, and one at 115,000 km runs about $2,000 under it. Handy math when you're staring at two listings priced the same but 40,000 km apart, one of them is the better deal and now you can prove it.
Over the last 90 days we flagged 8 GLBs from this year as deals. That's a steady trickle rather than a flood, so a genuinely priced-right one won't sit forever. Anchor on the $26,395 median, adjust for the odometer using that $673 rule, and you'll know within a few hundred dollars whether a seller is being fair.
