You should prioritize a history report first, then inspect the car closely for signs of prior damage, uneven wear, or deferred maintenance.

A careful pre-purchase inspection matters most if you want to avoid surprises in a premium sedan like this.

Is now a good time to buy a used 2020 Audi A6?

This looks like a moderate, selective buyer’s market, so you can shop carefully without expecting a deep bargain on every listing.

• Deal availability: 36.7% of listings are priced as good or great deals.
• Inventory: There are 501 listings available.
• Price trend: Prices have softened 11.27% compared with last year.
• Clean inventory: 75.6% of listings are accident-free.

If you find a listing below $22,646, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Audi A6's resale value?

The current average of $22,651 sits slightly below last year's $25,529.

That decline suggests the market has already adjusted downward, which can help you as a buyer but may limit upside if you plan to resell soon. For a future seller, the key takeaway is that pricing discipline matters: a well-kept example with strong equipment and clean history should be easier to move than one with questionable condition. The model’s premium positioning and broad appeal should still support demand, especially if you buy at the right price.

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

Should I buy a 2020 Audi A6 or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 36.7% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.6% — always verify the vehicle history report.
• Price trend: Prices have softened 11.27% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $21,929, the 2019 costs less than the current year's $22,651 average.
• It introduced a redesigned cabin with advanced technology and a more modern feel.

The bottom line: If you want the better-balanced shopping opportunity, the 2020 is the stronger primary choice because it combines a lower current average price, solid deal availability, and strong owner satisfaction. If you are especially price-sensitive, the 2019 is worth a look because it undercuts the 2020 on average price while still delivering a redesigned, tech-forward luxury sedan experience.
