Accident-free inventory is solid at 82.3% — always verify the vehicle history report.

You should prioritize a pre-purchase inspection that focuses on wear items, electronics, and signs of prior damage. Because some owners mention past accident records and wear-and-tear concerns, condition matters as much as mileage. A clean history report is important, but you should also make sure the car’s features, interior, and driving behavior all match the seller’s claims.

What is the 2021 Audi A6's resale value?

The current average of $26,259 sits slightly below last year's $28,352.

That price movement suggests the market has cooled, which can make the car easier to buy now but may also limit upside if you plan to sell soon. For future sellers, the softer pricing means you should pay close attention to condition, mileage, and service history if you want to protect value. Well-kept examples should hold up better than average because buyers still respond to the A6’s premium feel and feature content.

Vehicles with solid owner satisfaction ratings, like this model year's 4.3/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 Audi A6 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:

• 38.8% of listings are priced as good or great deals.
• Accident-free inventory is solid at 82.3% — always verify the vehicle history report.
• Price trend: Prices have softened 7.38% compared with last year.
• Owners rate it 4.3/5 — a solid satisfaction signal.

The bottom line: You should lean toward the 2021 if you want a well-equipped, tech-forward A6 at a softer used-car price than last year. If your priority is stretching your budget further, a nearby model year may be worth comparing, but the 2021 is the better primary target when you want a balance of value, features, and owner satisfaction.
