The median 2018 Audi S4 sits at $27,995 in the Canadian market right now. Most of these cars land between $24,899 and $30,500, so anything at or under $28k with average kilometres is fair money. The typical example has run about 122,988 km.

That roughly $5,600 spread from the bottom to the top of the range is your negotiating room. A car priced near $30,500 needs to justify it with low kilometres or a clean history. If a seller is asking near the top and the odometer reads well past 123,000, you've got a case to push back.

What kilometres cost you

Mileage moves the price in a way you can actually put a number on. Every extra 10,000 km knocks about $1,245 off. So a car with 150,000 km should run roughly $3,400 under one sitting at the 123,000 median, all else equal. Run that math before you fall for a low sticker on a high-kilometre car.

We've flagged 5 deals on this model year in the last 90 days. Not a flood, but enough that a well-priced one shows up if you're watching. Know the $27,995 median cold, and you'll spot the difference between a real deal and a car that's just wearing a discount.
