The median 2015 Cayenne in the Canadian market sits at $23,500. Most of what's listed lands between $21,900 and $27,000, so anything under $22k is priced at the low edge of normal, and once you're pushing past $27k the seller wants a premium you should be able to justify.
Median odometer reading is 151,100 km. That's the number to anchor on. A car with 120,000 km isn't automatically overpriced at $27k, and a 190,000 km example asking $24k is leaning on its trim or condition to hold that line.
What to pay
The $5,100 spread from bottom to top of the typical range is where the negotiation lives. Land near $21,900 and you're buying at the floor of what's reasonable for this year. Somewhere in the low-to-mid $20s, close to that $23,500 median, is the honest middle for a car around 151,000 km.
If you're looking at the top of the band, treat $27,000 as the ceiling, not a starting point. Above it, you're paying for something specific, whether that's low kilometres or a loaded example, and the odometer and equipment should back it up before you agree.
