What is the 2018 Audi A4's resale value?

The current average of $18,067 CAD sits slightly below last year's $21,896 CAD.

That price movement suggests the market has already adjusted downward, which can make the car more approachable for you now, but it also means future resale gains may be limited if depreciation continues at a similar pace.

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