At 66.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can separate clean examples from cars with prior damage. Then prioritize a pre-purchase inspection, especially if the listing has incomplete service records or visible wear. Focus on condition details that matter most in a luxury sedan: interior wear, electronics, and signs of uneven repair quality.

What is the 2018 Audi A6's resale value?

The current average of $16,577 sits slightly below last year's $18,493.

That price movement suggests the market has already adjusted downward, which can help you buy more confidently now but may also limit near-term upside if you plan to resell soon. If you keep the car in strong condition and maintain it well, you can help protect value better than the broader market trend suggests. Strong presentation and documented care matter more when the model is already trending softer.

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:

• 33.2% of listings are priced as good or great deals.
• At 66.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.36% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $21,979, the 2019 costs more than the current year's $16,577 average.
• The 2019 brings a redesigned cabin and more advanced MMI and driver-assistance tech.

The bottom line: If you want the better value play, the 2018 is the stronger starting point because it combines a lower average price with solid owner satisfaction. If you care more about newer technology and a more modern redesign, the 2019 is the better upgrade path, but you'll pay more for it. For price-sensitive buyers, the 2018 is the more compelling buy.
