Used 2020 Audi A6 for Sale near Illinois

How much does the 2020 Audi A6 cost?

Prices have softened 11.49% compared to this time last year, making it a favorable time to shop this model year.

There are 507 listings available, which suggests a healthy amount of inventory to compare.

If you find a listing below $22,700.84, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 Audi A6 a good car?

Yes — the 5/5 user rating points to strong owner satisfaction.

The 2020 Audi A6 stands out as a fifth-generation luxury sedan that brought a larger body, a new aluminum-and-steel chassis, and a major technology upgrade. You get standard Apple CarPlay and Android Auto, dual screens, lots of connectivity, semi-autonomous capability, and standard quattro all-wheel drive, which makes it especially appealing if you want a refined sedan with confident all-weather traction.

It is also a strong fit if you value understated luxury and a premium cabin over bargain pricing. 33.1% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2020 Audi A6 reliable?

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

The 2020 Audi A6 is presented as a well-equipped luxury sedan with standard all-wheel drive, a modern chassis, and a strong list of standard and available features. That combination points to a vehicle designed for comfort, capability, and everyday usability rather than a stripped-down ownership experience.

For used buyers, the main long-term risk is that a premium sedan with this much technology and equipment can be more expensive to keep in top shape if prior maintenance was inconsistent.

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

At 74.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

Start with a vehicle history report so you can confirm accident records, title status, and service history before you go any further. Then prioritize a pre-purchase inspection, especially on cars with higher mileage or visible cosmetic wear, because condition matters a lot in a premium sedan like this. Focus on signs of uneven panel gaps, interior wear, electronics behavior, and evidence that the car has been maintained consistently.

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

This is a moderate market for selective buyers, with enough inventory to shop carefully and enough deal activity to reward patience.

• Deal availability: 33.1% of listings are priced as good or great deals.
• Inventory: There are 507 listings available.
• Price trend: Prices have softened 11.49% compared with last year.
• Clean inventory: 74.6% of listings are accident-free.

If you find a listing below $22,700.84, 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 $22,853 sits slightly below last year's $25,819.

That decline suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For a future seller, that also means resale value will depend heavily on how well the car is maintained and how clean its history is. A well-kept example should hold up better than one with accident history or visible wear.

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:

• 33.1% of listings are priced as good or great deals.
• At 74.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.49% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $21,979, the 2019 costs less than the current year's $22,853 average.
• It introduced a redesigned cabin with a modern MMI system and advanced tech.

The bottom line: If you want the stronger all-around used-buying case, the 2020 is the better primary target because it combines a lower current average price with broad inventory and strong owner satisfaction. If your priority is saving money upfront, the 2019 is the better secondary path, especially if you find a clean example with the features you want.
