At 62.9% 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 prior damage was repaired properly. Then prioritize a pre-purchase inspection so you can check for signs of uneven wear, poor repairs, or cosmetic shortcuts. Focus closely on overall condition, since owner feedback suggests that some listings may vary more than others in how well they were maintained.

What is the 2018 Audi A5's resale value?

The current average of $19,449 sits slightly below last year's $20,369.

That softer pricing suggests the market has already adjusted downward, which can help you buy at a more favorable entry point. If you plan to sell later, the current trend means your resale outcome will depend heavily on how well you preserve condition and how carefully you choose your purchase price today. A well-bought example gives you a better chance of limiting depreciation pressure over time.

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 A5 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:

• 38.0% of listings are priced as good or great deals.
• At 62.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 4.52% compared with last year.

The bottom line:

You should lean toward the 2018 if you want the second-generation A5’s updated design, strong owner satisfaction, and a market that still offers some deal potential. If you are especially price-sensitive, a nearby year may be worth comparing, but the 2018 is the better primary target when you want the newer-generation package and are willing to shop carefully for condition and history.
