The overview describes it as a fifth-generation luxury sedan with a longer, wider body, a modern chassis, standard quattro all-wheel drive, and a major technology upgrade.

The overview also points to a well-equipped, modern design with standard all-wheel drive, a mild hybrid system, and a broad set of driver-assistance and convenience features.

What should I look for when buying a used 2020 Audi A6?

Accident-free inventory is solid at 75% — always verify the vehicle history report. You should also prioritize a pre-purchase inspection so you can confirm the condition of the drivetrain, electronics, and suspension-related features. Focus on signs of wear, incomplete maintenance, or any evidence that the car’s premium equipment has not been cared for properly.

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 every listing to be a bargain.

• Deal availability: 37.1% of listings are priced as good or great deals.

• Price trend: Prices have softened 12.26% compared with last year.

If you find a listing below $22,670, 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 $22,670 sits slightly below last year's $25,838. That kind of decline can help you buy more affordably now, but it also means future resale gains may depend on how well the market stabilizes. If you plan to sell later, a well-kept example with strong equipment and clean history should be easier to position against similar listings. The model’s premium features and broad appeal can help support demand, especially if you keep mileage and condition in check.

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:

• 37.1% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75% — always verify the vehicle history report.
• Price trend: Prices have softened 12.26% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $22,011, the 2019 costs less than the current year's $22,670 average.
• It emphasizes a redesigned cabin with major technology updates.

The bottom line: You should lean toward the 2020 if you want the newer-year value proposition, strong inventory, and a broad feature set at a softened price. If your priority is spending less upfront, the 2019 is the better secondary path because it undercuts the current year’s average while still delivering a redesigned, tech-forward luxury sedan.
