What is the 2018 Audi A6's resale value?

The current average of $16,594 sits slightly below last year's $18,630.

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 is documented. If you keep the car clean, well maintained, 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 2018 Audi A6 or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 33.3% of listings are priced as good or great deals.
• At 66.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.93% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $22,064, the 2019 costs more than the current year's $16,594 average.
• The 2019 brings a redesigned cabin with updated MMI and more advanced driver assistance.

The bottom line: If you want the better value today, the 2018 is the smarter starting point because it combines a lower average price with strong owner satisfaction. If you’re willing to pay more for a newer redesign and updated technology, the 2019 is the better secondary path for buyers who prioritize the latest cabin and driver-assistance upgrades.
