How much does the 2021 Audi A6 cost?

Prices have softened 13.18% compared to this time last year, making it a favorable time to shop this model year.

With 250 listings available, you have a meaningful amount of inventory to compare across price, mileage, and condition.

If you find a listing below $26,481.60, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2021 Audi A6 a good car?

Generally — the 4.25/5 user rating points to a strong ownership experience for this model year. Owners consistently praise the high-tech features, smooth driving experience, and performance in various weather conditions.

That lines up well with the A6’s use-case as a premium midsize sedan that feels modern and well equipped, especially if you want standard all-wheel drive and a cabin built around connectivity and everyday usability. The market also shows 31.6% of listings as good or great deals, which gives you some room to shop selectively.

Is the 2021 Audi A6 reliable?

Owners rate it 4.25/5, a solid signal of long-term satisfaction.

The review summary also points to reliability, dependability, and a trouble-free feel as part of the ownership appeal, especially for buyers who want a car they can count on over time. That said, some owners mention wear and tear concerns, so a used example with a clean maintenance history matters more than usual.

For used buyers, the main long-term ownership risk is ending up with a car that has been driven hard or poorly maintained, so condition and records should carry real weight in your decision.

What should I look for when buying a used 2021 Audi A6?

Accident-free inventory is solid at 81.2% — always verify the vehicle history report.

You should still run a history report on every candidate, even if the listing looks clean at first glance. Prioritize a pre-purchase inspection, especially if the car has higher mileage or incomplete service documentation.

Focus on overall condition, not just features, because wear and tear can matter more than equipment on a used luxury sedan. If possible, compare multiple examples side by side so you can spot differences in maintenance, cosmetic condition, and prior damage.

Is now a good time to buy a used 2021 Audi A6?

What is the 2021 Audi A6's resale value?

The current average of $26,466 sits slightly below last year's $30,484.

That decline suggests the market has already adjusted downward, which can help you as a buyer today but may limit upside if you plan to resell soon. For a future seller, the key takeaway is that pricing discipline matters: buying well now gives you a better chance of preserving value later.

Vehicles with solid owner satisfaction ratings, like this model year's 4.25/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 Audi A6 or consider a different year?
