Set your anchor at $29,194. That's the median asking price for a 2018 Lexus IS in the Canadian market, with a typical odometer reading around 108,900 km. If a car sits near that number with mileage in the same ballpark, you're looking at a fair-market deal, not a steal and not a rip-off.
Most of the action lands between $25,799 and $32,500. Anything under $25,799 deserves a hard look at the history and condition, because it's priced below where the bulk of clean examples live. Anything over $32,500 needs to justify itself with low kilometres or a loaded spec, otherwise you're paying a premium for the badge.
What mileage does to the price
Every 10,000 km knocks about $692 off the asking price. So a car with 80,000 km should command roughly $2,000 more than one at 108,900, and a higher-mileage example sitting near 140,000 km fairly trades for around $2,000 less than the median. Run that math against any listing before you negotiate. It's the fastest way to tell whether the seller priced the odometer honestly.
