CarGurus Analysis: 2021 GMC Terrain
Summary
With 137 currently listed for sale and an average price of $18,588, 41.6% of 2021 GMC Terrain listings on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 GMC Terrain 5 / 5 stars.
89.8% of 2021 GMC Terrain listings on CarGurus are accident free.
Why it stands out
The 2021 GMC Terrain stands out as a compact SUV that leans more premium and polished than many rivals. It shares its basic hardware with the Chevrolet Equinox, but GMC gives the Terrain a more angular look and a more upscale feel inside. For this generation, Apple CarPlay and Android Auto are standard, and many models feature an eight-inch touchscreen. The Terrain also benefits from a push-button gear selector, better sound insulation, and a slightly smarter interior, which help it feel a bit more refined than its mainstream positioning might suggest.
For 2021, the Terrain’s lineup was simplified around a 1.5-liter turbocharged engine, since the larger 2.0-liter engine option was dropped. That engine makes 170 horsepower and works with a nine-speed automatic transmission. Buyers who want a used Terrain for everyday driving may appreciate its comfortable ride, roomy cabin, and good safety equipment, while the model’s value proposition is strengthened by its generally good reliability scores and lower prices than some Japanese rivals. At the same time, cargo space is not a strong point, and the 1.5-liter engine is not the best choice for buyers who want stronger acceleration or maximum towing ability.

Very nice interior. Excellent options. We went with a black on black model but would have purchased this one if the other had not been available.

I absolutely adore my Terrain! I love everything about it. Not too big, not too small. Zero complaints. If I did have to make a suggestion I would say blind spot protection, and maybe a bigger screen that shows your speed but not deal breakers and simply just suggestions :)

How much does the 2021 GMC Terrain cost?
| Metric | Value |
|---|---|
| Current Average Price | $17,780 |
| Year-Round Low | $17,780 |
| Year-Round High | $20,039 |
| Average Price a Year Ago | $20,041 |
| Change vs. Last Year | −11.28% |
Prices have softened 11.28% compared to this time last year, making it a favorable time to shop this model year.
There are 2,415 listings available, which suggests you have a solid amount of inventory to compare.
Is the 2021 GMC Terrain a good car?
Yes — the 2021 GMC Terrain earns a 5/5 user rating, which points to strong owner satisfaction.
Drivers consistently praise its stylish interior, feature set, smooth ride, and fuel efficiency. The Terrain’s use-case appeal is strongest if you want a compact SUV that feels a bit more premium than many rivals while still serving as an everyday commuter with a comfortable cabin.
With 34.3% of listings marked as good or great deals, you have a meaningful chance to find attractive pricing.
Is the 2021 GMC Terrain reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The owner feedback also emphasizes value, smooth driving manners, and a generally dependable ownership experience, which are all encouraging signs if you want a used SUV you can count on. For used buyers, that kind of satisfaction lowers the odds of unpleasant long-term surprises, though condition and maintenance history still matter.
What should I look for when buying a used 2021 GMC Terrain?
At 74% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should run a vehicle history report on any promising listing and prioritize a pre-purchase inspection before you commit. Focus closely on body condition, signs of prior repair, and whether the cabin and technology features match the seller’s description.
Is now a good time to buy a used 2021 GMC Terrain?
This looks like a moderate, selective buyer’s market, so you can shop patiently and still find worthwhile options.
- Deal availability: 34.3% of listings are priced as good or great deals.
- Inventory: There are 2,415 listings available.
- Price trend: Prices have softened 11.28% compared with last year.
- Clean inventory: 74.0% of listings are accident-free.
If you find a listing below $17,780, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2021 GMC Terrain's resale value?
The current average of $17,780 sits slightly below last year's $20,041.
That price movement suggests the Terrain has already absorbed a meaningful amount of depreciation, which can help future sellers if the market stabilizes. If you buy at a disciplined price today, you may have a better chance of limiting your loss when it’s time to sell. Strong owner satisfaction can also help keep demand steady in the used market.
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 2021 GMC Terrain 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:
- 34.3% of listings are priced as good or great deals.
- At 74% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 11.28% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
Consider the 2022 if:
- At $21,088, the 2022 costs more than the current year's $17,780 average.
- It adds an AT4 trim with standard all-wheel drive and rugged styling.
The bottom line: If you want the better value, the 2021 is the stronger buy because it combines lower pricing with strong owner satisfaction. If you’re willing to spend more for a newer model and a more rugged trim option, the 2022 is the better secondary path.
