The median 2012 GLK-Class in the Canadian market sits at $9,500. Most of what's listed lands between $8,000 and $9,999, so if you're paying much north of ten grand, you're above where this year normally trades.
That typical range is tight. Under $2,000 separates the low end from the high end, which tells you the market has settled on a fairly consistent value for a 2012 GLK. A car priced at $8,000 isn't a scam and one at $9,900 isn't a rip-off. Both fall inside normal.
What to expect on the odometer
The median example has 182,916 km on it. That's a car well into its second life, so budget accordingly and read that $9,500 median as the going rate for a GLK carrying roughly that kind of distance. A cleaner, lower-km example can justify sitting at the top of the range, and something near the median mileage belongs closer to the middle of the band.
One more signal worth knowing: we flagged 5 of these as deals in the last 90 days. Not a flood, but enough to say fairly priced 2012 GLKs do surface if you're patient rather than grabbing the first one you see.
