CarGurus Analysis: 2020 GMC Terrain
Summary
With 58 currently listed for sale and an average price of $20,788 CAD, 37.9% of 2020 GMC Terrain listings on CarGurus are rated as good or great deals.
Favourably reviewed: Owners rated the 2020 GMC Terrain 4.4 / 5 stars.
Why it stands out
The 2020 GMC Terrain stands out as a compact SUV that leans more toward comfort and premium feel than outright ruggedness. It was part of the second generation, which gave the Terrain distinct styling inside and out, along with features such as a push-button gear selector, better sound insulation, and a slightly smarter interior. For buyers shopping used, that combination helps the Terrain feel a bit more upscale than many rivals, while still remaining a practical small SUV.
For 2020, the Terrain lineup was updated and important safety technology became standard, including automatic emergency braking, forward collision alert with pedestrian detection, lane keep assist, lane departure warning, and automatic high beams. The diesel engine was dropped that year, and the Terrain Denali received an upgraded suspension package to improve its ride and handling. The 2020 GMC Terrain Denali is also notable for pairing the more powerful 252-horsepower engine with that improved suspension package, making it the standout choice in the range for buyers who want a stronger, more polished drive.
There are still trade-offs to consider. The second-generation Terrain’s cargo capacity behind the rear seat trailed that of its most popular rivals, and the 1.5-litre turbocharged engine’s highway acceleration isn’t very good. Even so, the Terrain’s good reliability scores, comfortable cabin, and strong safety equipment make it appealing for shoppers who value a well-equipped, easy-to-live-with compact SUV.

Is the 2020 GMC Terrain a good car?
Generally — the 2020 GMC Terrain earns 4.4/5, which points to strong owner satisfaction. Owners commonly praise its comfort and safety features, along with its spacious interior and economical performance. The Terrain also fits well if you want a compact SUV with a more premium feel, a comfortable cabin, and everyday practicality. With 33.8% of listings marked as good or great deals, you still have some room to shop carefully.
Is the 2020 GMC Terrain reliable?
Owners rate it 4.4/5, a solid signal of long-term satisfaction.
The owner feedback points to a dependable, trouble-free experience for many shoppers, with comfort and safety standing out as recurring strengths. That kind of long-term approval matters if you want a used SUV you can count on for daily driving. For used buyers, the main ownership risk is making sure the specific vehicle has been maintained properly, since any used SUV can carry age-related wear.
Is now a good time to buy a used 2020 GMC Terrain?
This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you’re patient and compare listings carefully.
- Deal availability: 33.8% of listings are priced as good or great deals.
- Inventory: There are 213 listings available.
- Price trend: Prices have softened 11.44% compared with last year.
If you find a listing below $20,066 CAD, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2020 GMC Terrain's resale value?
The current average of $20,066 CAD sits slightly below last year's $22,659 CAD.
That softer pricing can help you buy in at a more favourable point, but it also means future resale gains may be more limited if the market stays soft. If you plan to sell later, the current trend suggests you should focus on buying well and keeping the vehicle in strong condition. Vehicles with solid owner satisfaction ratings, like this model year's 4.4/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2020 GMC Terrain or consider a different year?

Choose the 2020 if:
- 33.8% of listings are priced as good or great deals.
- Price trend: Prices have softened 11.44% compared with last year.
- Owners rate it 4.4/5 — a solid satisfaction signal.
The bottom line: You should lean toward the 2020 if you want a compact SUV with a more premium feel, strong owner satisfaction, and a market that still offers some deal potential. If your priority is stretching your budget further, a nearby model year may be worth comparing, but the 2020 remains the better pick when comfort, safety, and overall satisfaction matter most.
