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

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

• Deal availability: 23.4% of listings are priced as good or great deals.
• Inventory: There are 167 listings available.
• Price trend: Prices have softened 17.31% compared with last year.

If you find a listing below $17,955 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Audi A4's resale value?

The current average of $18,068 CAD sits slightly below last year's $21,849 CAD.

That price movement suggests the market has become more buyer-friendly, which can make resale planning a little more challenging if you buy at the wrong point in the cycle. If you’re a future seller, the softer pricing means you may need to be more competitive when it’s time to list. On the other hand, buying after a notable drop can help you limit depreciation exposure if you keep the car for several years.

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 A4 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:

• 23.4% of listings are priced as good or great deals.
• Price trend: Prices have softened 17.31% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: If you want a used luxury sedan with strong owner satisfaction and a market that has cooled enough to create some negotiating room, the 2018 is a sensible place to focus. If your priority is stretching your budget as far as possible, you can also compare nearby years to see whether a lower-priced alternative gives you similar appeal for less money.
