Owners rate it 4.75/5, a strong signal of long-term satisfaction. The 2021 A4’s appeal comes from its balanced design, updated technology, and everyday usability, all of which support confidence in ownership. Its mild-hybrid setup and available quattro all-wheel drive also add to its well-rounded character.

What should I look for when buying a used 2021 Audi A4?

At 74.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. Then prioritize a thorough pre-purchase inspection, especially if the car has higher mileage or incomplete service records. Focus on overall condition, because the best used A4 is the one that shows clean maintenance, consistent wear, and no signs of hidden body or mechanical issues.

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

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you’re patient.

• Deal availability: 38.7% of listings are priced as good or great deals.
• Inventory: There are 364 listings available.
• Price trend: Prices have softened 7.66% compared with last year.

If you find a listing below $21,477, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Audi A4's resale value?

The current average of $21,611 sits slightly below last year's $23,403.

That softer pricing can help you buy at a more favorable entry point, but it also means future resale gains may be more limited if the market stays soft. If you plan to sell later, condition and mileage will matter even more because buyers will likely compare your car against a fairly broad set of similarly priced listings. A clean history and strong maintenance record should help your car stand out when it’s time to move on.

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 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:

• 38.7% of listings are priced as good or great deals.
• At 74.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.66% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.

Consider the 2022 if:

• At $22,833, the 2022 costs more than the current year's $21,611 average.
• It feels fresher and brings stronger overall appeal, with modern tech and a more polished driving impression.

The bottom line: If you want the better value play, the 2021 is the primary path because pricing has eased and deal availability is solid. If you’re willing to pay more for a newer-feeling alternative, the 2022 is the better secondary path for buyers who prioritize freshness over savings.
