Is now a good time to buy a used 2021 Audi A4?

It looks like a buyer’s market right now, with pricing down and a solid share of attractive listings.

• Deal availability: 40.4% of listings are priced as good or great deals.
• Inventory: There are 47 listings available.

What is the 2021 Audi A4's resale value?

The current average of $24,899 CAD sits slightly below last year's $31,046 CAD.

That softer pricing can help you buy at a more favourable point in the cycle, but it also means future resale gains may be more limited if the market stays soft. If you plan to sell later, buying closer to the lower end of the range can help protect your equity. Strong demand for well-priced examples should still support values better than average.

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.

Should I buy a 2021 Audi A4 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 40.4% of listings are priced as good or great deals.
• Price trend: Prices have softened 19.80% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.

Consider the 2022 if:

• At $28,462 CAD, the 2022 costs more than the current year's $24,899 CAD average.
• It adds a fresher-feeling cabin with strong technology and safety appeal.

The bottom line: The 2021 is the better value if you want the lower entry price and a healthier share of good deals. If you can stretch your budget, the 2022 is the better pick for buyers who want the newer-year feel and are willing to pay more for it.
