The user feedback also points to a car that many owners found dependable and trouble-free enough to enjoy over time, especially when equipped with the stronger 3.0T engine.

At 66.1% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report on every candidate and confirm whether any prior damage was repaired properly. A pre-purchase inspection should be a priority, especially if the car has higher mileage or incomplete service documentation. Focus on overall condition, panel alignment, interior wear, and how well the technology and comfort features operate.

Is now a good time to buy a used 2018 Audi A6?

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you stay disciplined.

• Deal availability: 33.0% of listings are priced as good or great deals.
• Inventory: There are 658 listings available.
• Price trend: Prices have softened 8.93% compared with last year.

If you find a listing below $16,139, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Audi A6's resale value?

The current average of $16,139 sits slightly below last year's $17,721.

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 may depend more on condition, mileage, and documentation than on broad market momentum. Well-kept examples should still attract interest, but you may need to price competitively if you plan to sell later.

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:

• 33.0% of listings are priced as good or great deals.
• At 66.1% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.93% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $21,281, the 2019 costs more than the current year's $16,139 average.
• It brings a redesigned cabin with a more advanced interface and updated 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 and meaningful deal availability. If you’re willing to spend more for a newer redesign and more advanced tech, the 2019 is the better secondary path. For price-sensitive buyers, the 2018 is the one to watch first.
