The median 2010 Lexus IS in the Canadian market sits at $12,444. That's your anchor. Half of what's out there asks less, half asks more, and the typical range runs from $10,995 up to $18,946. So a solid, fairly priced example lands right around $11k to $13k.
The stretch above the median is wide. Cars in the $17k-$19k band are usually low-kilometre or loaded examples, and the gap between them and a $12k car is real money. If you're paying near $19k, you want to know exactly what justifies the roughly $6,500 premium over the median before you sign.
How mileage moves the price
Every 10,000 km knocks about $389 off the asking price. The median car has already run 173,346 km, so most of what you'll see has covered serious ground. A car sitting 40,000 km below that median should run you roughly $1,500 cheaper on mileage alone. Use that as a check: if two cars are priced the same but one has 30,000 km more on it, the higher-km one is quietly overpriced by around $1,150.
CarSignal flagged 6 deals on this model year in the last 90 days. Not a flood, but enough that below-median asking prices do surface if you're watching. Given the $389-per-10,000km slope, the smart play is to pay under $12,444 for anything near or above the median mileage, and reserve the top of the range for a genuinely low-kilometre car.
