Is the 2018 Audi A6 a good car?

Yes — the 2018 Audi A6 earns a 5/5 user rating, which points to very strong owner satisfaction.

Drivers consistently praise the interior design, the powerful performance, and the luxurious ride. The handling and feature content also come up often as strengths, which fits a sedan that aims to balance comfort with a polished driving feel.

For you, that means this model year makes the most sense if you want a refined used luxury sedan with a premium cabin and a well-rounded personality. 29.3% of listings are priced as good or great deals, so there are still some attractive opportunities in the market.

Is the 2018 Audi A6 reliable?

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

The owner feedback also points to a dependable-feeling ownership experience, with praise centered on the car’s overall quality, performance, and the sense that it delivers a trouble-free luxury experience for many drivers. That kind of feedback matters when you’re shopping used, because it suggests the car can be one you feel confident counting on over time.

For used buyers, the main long-term ownership risk is less about the rating itself and more about making sure the specific car you choose has been maintained properly.

What should I look for when buying a used 2018 Audi A6?

At 64.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any reported damage was minor or more serious. After that, prioritize a pre-purchase inspection so you can check for signs of uneven wear, repair quality, and any issues that might not show up in photos.

Focus on overall condition, service records, and how the car presents in person, since a clean-looking listing is not the same as a clean history. If you’re comparing multiple cars, the best choice is usually the one with the strongest documentation and the most consistent maintenance story.

What is the 2018 Audi A6's resale value?

The current average of $16,799 sits slightly below last year's $18,304.

That price movement suggests the model has already absorbed some depreciation, which can help future sellers if they buy at the right price today. If you purchase near the lower end of the range and keep the car in strong condition, you may be better positioned when it’s time to resell.

Strong owner satisfaction also helps support demand in the used market. 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:

• 29.3% of listings are priced as good or great deals.
• At 64.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.22% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $21,992, the 2019 costs more than the current year's $16,799 average.
• The redesign brings a more modern MMI system and advanced 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 design and updated technology, the 2019 is the better upgrade path; if price matters most, the 2018 is the smarter buy.
