CarGurus Analysis: 2019 GMC Terrain

Summary
With 64 currently listed for sale and an average price of $17,880 CAD, 28.1% of 2019 GMC Terrain listings on CarGurus are rated as good or great deals.
Favourably reviewed: Owners rated the 2019 GMC Terrain 5 / 5 stars.
Why it stands out
The 2019 GMC Terrain stands out as a compact SUV that leans more premium than many of its rivals. It shares its basic hardware with the Chevrolet Equinox, but GMC 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. That more upscale approach helps explain why it appeals to buyers who want a small utility vehicle with a more polished feel.
For 2019, the Terrain came standard with a 1.5-litre turbocharged engine producing 170 horsepower, while a 252-horsepower 2.0-litre turbocharged four-cylinder was optional with most models and standard with the top-shelf Denali trim. A nine-speed automatic was standard with both gasoline engines, and a unique 1.6-litre diesel engine was also offered in 2019. The diesel’s 137 horsepower was modest, but its 240 lb-ft of torque and excellent fuel economy made it the efficiency choice, especially for highway driving.
There are trade-offs, though. The second-generation Terrain’s cargo space behind the rear seat trailed that of its most popular rivals, and the 1.5-litre engine’s highway acceleration is not very good. Even so, the 2019 Terrain remains appealing for shoppers who value a comfortable cabin, strong safety equipment and good value on the used market.

Great look like no other. Its moon shape headlights make it give great illumination and it looks like a real 2020 car. For real gas saver. I personally would love they would make it a foot longer to accommodate a 3rd row seats. Awesome look great stability. Competitive price.

- Deal availability: 28.6% of listings are priced as good or great deals.
- Inventory: There are 234 listings available.
- Price trend: Prices have softened 16.06% compared with last year.
If you find a listing below $18,380 CAD, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2019 GMC Terrain's resale value?
The current average of $18,600 CAD sits slightly below last year's $22,159 CAD.
That price movement suggests the Terrain has become more affordable for you as a buyer, but it also means a future seller may face a softer resale environment than owners saw a year ago. If you buy now, the lower entry price can help offset some depreciation risk. The model’s premium-leaning image and strong owner satisfaction should still support demand better than a less distinctive competitor.
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 2019 GMC Terrain or consider a different year?
If you're weighing the 2019 against nearby model years, here's how to think about it:
Choose the 2019 if:
- 28.6% of listings are priced as good or great deals.
- Price trend: Prices have softened 16.06% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
The bottom line: The 2019 Terrain makes sense if you want a compact SUV with a more premium feel, strong owner approval, and a market that currently gives you some negotiating room. If you are especially price-sensitive, you can also compare nearby years to see whether a lower asking price outweighs the 2019’s strong satisfaction and value profile.
