Is now a good time to buy a used 2021 Hyundai Sonata?

This is a moderate market for selective buyers, so it makes sense to compare listings carefully and move quickly on strong examples.

• Deal availability: 29.3% of listings are priced as good or great deals.
• Inventory: There are 123 listings available.
• Price trend: Prices have softened 18.09% compared with last year.

If you find a listing below $19,103 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Hyundai Sonata's resale value?

The current average of $19,103 CAD sits slightly below last year's $23,321 CAD.

That price drop suggests the market has become more buyer-friendly, which can make it harder for a future seller to command top dollar right away. If you buy now, you may benefit from the softer pricing, but resale gains could be more gradual if the market stays at this level.

The current average also sits near the low end of the year-round range, which means future depreciation may be less severe if demand remains steady. Vehicles with strong owner satisfaction ratings, like this model year's 4.75/5, tend to retain buyer demand, which supports resale value over time.

It comes with Hyundai’s collection of advanced driving assistance systems, including adaptive cruise control with stop-and-go, forward-collision warning with pedestrian and cyclist detection, automatic emergency braking, lane-departure warning, lane-keeping assist, lane-centring assistance, blind-spot warning, rear cross-traffic warning, driver-attention warning, automatic high-beam headlights, Rear Occupant Alert, Safe Exit Warning, and Highway Drive Assist.

The review also notes that the standard Sonata rates high for occupant protection in a collision, but the N Line had not been tested independently at the time. That means you should pay close attention to the exact trim and equipment level when comparing used examples.

Should I buy a 2021 Hyundai Sonata or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 29.3% of listings are priced as good or great deals.
• Price trend: Prices have softened 18.09% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.
• The 2021 stands out as a rare traditional sport sedan with strong performance and practicality.

Consider the 2022 if:

• At $22,290 CAD, the 2022 costs more than the current year's $19,103 CAD average.
• It adds a broader personality and a surprisingly sporty N Line variant.

The bottom line: If you want the best mix of value, performance, and current market pricing, the 2021 is the smarter buy. If you are willing to spend more for a newer model year with a broader appeal, the 2022 is worth a look. For price-sensitive shoppers, the 2021’s softer pricing makes it the more compelling starting point.
