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

A careful test drive should also confirm that the car feels smooth, quiet, and consistent in everyday use.

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 patiently but should move quickly on the best listings.

• Deal availability: 37.7% of listings are priced as good or great deals.
• Inventory: There are 486 listings available.
• Price trend: Prices have softened 12.71% compared with last year.
• Clean inventory: 75.3% of listings are accident-free.

If you find a listing below $21,598, 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 $21,598 sits slightly below last year's $24,745.

That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable entry point. For a future seller, that also means resale value will depend heavily on condition, mileage, and how well the car has been maintained. If you keep the car clean, documented, and accident-free, you give yourself a better chance of standing out when it’s time to sell.

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:

• 37.7% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.3% — always verify the vehicle history report.
• Price trend: Prices have softened 12.71% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $20,933, the 2019 costs less than the current year's $21,598 average.
• It offers a newly redesigned luxury sedan with modern tech and a fresh cabin layout.

The bottom line: If you want the stronger current-market balance of price, inventory, and satisfaction, the 2020 is the better primary target. If your top priority is spending less up front, the 2019 is the smarter secondary path.
