A 2015 C-Class in Canada runs about $15,948 at the midpoint right now. Most of the market clusters between $13,967 and $18,195, so anything under $14K is worth a hard look and anything over $18K needs a reason to justify the premium. That $4,200 spread is your negotiating room.
The typical car on offer has around 138,390 km on it. Keep that number in your head as a baseline. It's the yardstick for judging whether a given listing is priced fairly or leaning on low kilometres to ask more.
What mileage does to the price
Every extra 10,000 km knocks roughly $540 off the asking price. So a car sitting at 170,000 km should come in around $1,700 below one near the 138K median, all else equal. Flip it around: if a seller wants a premium for a lower-odometer car, about $540 per 10,000 km under the median is the ceiling on what that's reasonably worth.
Run the math before you talk price. A 2015 C-Class advertised at $17,500 with 180,000 km is asking more than the median while carrying well above-average wear. That's the kind of listing where the number and the odometer don't agree, and it's your opening.
We've flagged 10 deals on this model year in the last 90 days. That's a steady trickle of cars priced below where the data says they should sit, so a patient buyer has room to wait for the right one rather than chase the first listing that shows up.
