What is the 2021 Audi Q3's resale value?

The current average of $24,365 CAD sits slightly below last year's $28,348 CAD.

That softer pricing can be a plus if you're buying now, but it also means future resale gains may be more limited unless the market tightens again. If you plan to sell later, buying at the lower end of the range can help protect your position. Stronger pricing today can also make it easier to recover value if demand stays steady.

Vehicles with strong owner satisfaction ratings, like this model year's 4.8/5, tend to retain buyer demand, which supports resale value over time.
