Is now a good time to buy a used 2018 Audi A4?

This is a moderate buyer’s market, so you can be selective without expecting every listing to be a bargain.

• Inventory: There are 168 listings available.
• Price trend: Prices have softened 15.90% compared with last year.

What is the 2018 Audi A4's resale value?

The current average of $18,279 CAD sits slightly below last year's $21,736 CAD.

That price movement suggests the market has cooled, which can make the car more attractive to you as a buyer today but may also limit upside for a future seller. If you buy at a strong price now, you may have a better chance of protecting your value later. The fact that demand remains supported by positive owner feedback helps, but resale will still depend heavily on condition, mileage, and maintenance history.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.
