CarGurus Analysis: 2021 GMC Terrain
Summary
With 212 currently listed for sale and an average price of $16,557, 37.7% 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.
84.4% 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 than many rivals, with a stylish interior and a strong feature set. It also benefits from the second-generation Terrain’s standard Apple CarPlay and Android Auto, plus an eight-inch touchscreen on many models, which helps it feel modern and easy to live with. For shoppers who want a small SUV that feels comfortable and well equipped without moving into a luxury badge, that combination is a major part of its appeal.
For 2021, the Terrain’s lineup was simplified around the 1.5-liter turbocharged engine, and that engine was the only choice that year. It produced 170 horsepower and came with a nine-speed automatic. The Terrain also offered a roomy cabin and good safety equipment, including automatic emergency braking, forward collision alert, lane-centering, lane-departure warning and front pedestrian braking. Owners often praise its smooth ride and fuel efficiency, which fit the Terrain’s easygoing character.
There are tradeoffs, though. The 2021 Terrain’s highway acceleration is not very good, and its cargo space trails some top rivals. It also lacks the maximum towing ability available in the broader second-generation range, and some interior materials can feel cheap. Even so, the 2021 GMC Terrain remains appealing for buyers who value comfort, a polished cabin and a generous list of standard technology and safety features.

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 :)

| Metric | Value |

| Year-Round High | $20,039 |
| Average Price a Year Ago | $20,041 |
| Change vs. Last Year | −11.28% |

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.
