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

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile opportunities.

• Deal availability: 26.7% of listings are priced as good or great deals.
• Inventory: There are 172 listings available.
• Price trend: Prices have softened 18.99% compared with last year.

If you find a listing below $17,812 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 $17,812 CAD sits slightly below last year's $21,988 CAD.

That softer pricing can work in your favour if you buy now, but it also means future resale gains may be more limited if the market stays soft. If you plan to sell later, buying at the lower end of the range gives you a better starting point. Strong condition and a clean service record will matter even more when the market is already pricing this model more cautiously.

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:

• 26.7% of listings are priced as good or great deals.
• Price trend: Prices have softened 18.99% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: The 2018 Audi A4 is a strong choice if you want a well-liked luxury sedan with solid market value and enough inventory to compare options. If you are price-sensitive, you may also want to compare nearby years to see whether a similar car is available at a lower asking price, but the 2018 stands out as a sensible primary target when you find one in good condition and priced near the lower end of the range.
