The median 2012 Mercedes-Benz GL-Class in Canada sits at $12,600. That's your anchor. If a seller is asking well north of that, they'd better have the paperwork to back it up.
Most of these land between $10,850 and $15,900. That's the typical range, and it's where you'll do the bulk of your shopping. Anything under $10,850 is worth a hard look, either it's a genuine deal or it's carrying something a listing photo won't show you. Above $15,900 you're paying a premium, so ask what justifies it.
What the mileage tells you
The median odometer reading here is 200,000 km. So a GL-Class at this price point is a high-kilometre vehicle by default, and the money reflects that. If you find one meaningfully below 200,000 km near the median price, that's the kind of listing worth chasing down before someone else does.
We flagged 4 deals on this model year in the last 90 days. Not a flood, but enough that decent buys do surface if you're watching. Know the $12,600 median cold, keep the $10,850 to $15,900 band in your head, and you'll spot a fair price the moment it shows up.
