At 62.8% 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 prior damage was repaired properly. A pre-purchase inspection should be a priority, especially if the car has incomplete records or signs of uneven wear. Focus on overall condition, repair quality, and maintenance consistency rather than just mileage or trim appearance.

Is now a good time to buy a used 2018 Audi A5?

This is a moderate market, so you can be selective without expecting a deep bargain on every listing.

• Deal availability: 39.6% of listings are priced as good or great deals.

What is the 2018 Audi A5's resale value?

The current average of $19,362 sits slightly below last year's $20,448.

That price movement suggests the market has already adjusted downward, which can help you as a buyer today but may limit upside if you plan to resell soon. If you buy at the right price and keep the car in strong condition, you can reduce the impact of future depreciation. The model’s strong owner satisfaction can also help support demand 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 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:

• 39.6% of listings are priced as good or great deals.
• At 62.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 5.31% compared with last year.

The bottom line:

The 2018 is the right pick if you want the second-generation A5’s updated design, broader body-style lineup, and strong owner satisfaction at a softened price point. If you’re especially price-sensitive, you can also compare nearby years to see whether a similar car offers a better deal or cleaner history, but the 2018 remains the most balanced choice when you want style, features, and value in one package.
