The median 2011 Audi S5 in the Canadian market sits at $15,999. If someone quotes you much above that for a comparable car, you've got room to push back.
Most of these land between $14,450 and $18,400. That $3,950 spread is your working zone. Cars near the bottom usually carry more wear or a spottier history, and the ones stretching toward $18,400 tend to be cleaner or better optioned. Anything priced above the top of that band needs a real reason attached to it.
What a fair number looks like
The typical 2011 S5 out there has about 160,000 km on the clock. Keep that in mind when you read a listing. A car at 160,000 km priced at $16,000 is squarely normal. One at $18,000 with the same distance is asking you to pay for something, and it should be obvious what.
We've flagged 4 deals on this model year in the last 90 days. That's the count of listings that came in genuinely underpriced against the market, so they do surface, just not every week.
Bottom line: budget around $16,000 for an average example, treat $14,450 as the floor for something you'll want to inspect closely, and let the odometer do most of the talking when you're comparing two cars.
