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:

• 33.0% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.3% — always verify the vehicle history report.
• Price trend: Prices have softened 7.69% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.

Consider the 2022 if:

• At $23,504, the 2022 costs more than the current year's $21,837 average.
• It feels fresher and more modern overall.

The bottom line: If you want the better value, the 2021 is the stronger starting point because it combines a lower average price with solid deal availability and strong owner satisfaction. If you’re willing to pay more for a newer-feeling alternative, the 2022 is the better secondary path.
