Is now a good time to buy a used 2021 Audi Q3?

• Inventory: There are 186 listings available.
• Price trend: Prices have softened 15.55% compared with last year.

What is the 2021 Audi Q3's resale value?

The current average of $24,891 CAD sits slightly below last year's $29,476 CAD.

That softer pricing can be a mixed signal for future resale: it may help you buy at a more attractive entry point now, but it also means there is less room for appreciation if the market stays soft. If you plan to sell later, buying well below the current average will matter more than usual. Vehicles with strong owner satisfaction ratings, like this model year's 4.75/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 Audi Q3 or consider a different year?
