CarGurus Analysis: 2021 GMC Terrain
Summary
With 144 currently listed for sale near Boston, MA and an average price of $16,869, 36.8% of 2021 GMC Terrains for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 GMC Terrain 5 / 5 stars.
95.8% of 2021 Terrain models on CarGurus are accident free.
Why it stands out
The 2021 GMC Terrain stands out as a compact SUV that leans more toward comfort, value, and everyday usability than outright performance. It offers a roomy cabin for four adults, or five at a pinch, and its smooth ride and fuel efficiency are recurring strengths. Owners also tend to appreciate the stylish interior and the generous feature set, which helps the Terrain feel well equipped for the money.
For 2021, the Terrain’s powertrain lineup was simplified to the 1.5-liter turbocharged engine, so buyers looking at this model year get a straightforward setup rather than a wide range of choices. That engine is paired with either a continuously variable automatic transmission in front-wheel-drive models or an eight-speed automatic with all-wheel drive, and all-wheel-drive versions also gain a higher towing capacity. The Terrain’s safety equipment is another highlight, with features such as adaptive cruise control, lane keep assist with lane departure warning, enhanced automatic emergency braking, front pedestrian and bicyclist braking, intersection automatic emergency braking, rear cross traffic braking, reverse automatic braking, side bicyclist alert, and blind zone steering assist.
The main tradeoff is cargo space. The Terrain has 30 cubic feet behind the rear seats and up to 64 cubic feet with them folded, which is smaller than some key rivals. Some owners also mention minor omissions, including the lack of a standard auto wiper feature and a desire for stronger blind spot protection. Even so, the 2021 GMC Terrain remains appealing for shoppers who want a comfortable, well-equipped small SUV with good efficiency and a polished feel.

It had everything and more in the features that I was looking for. I think it was a good value for all that it offered.

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 :)

I love the Terrain! It drives great and has a smoothest ride. It also is good on gas.

How much does the 2021 GMC Terrain cost?
| Metric | Value |
|---|---|
| Current Average Price | $18,320 |
| Year-Round Low | $18,320 |
| Year-Round High | $20,227 |
| Average Price a Year Ago | $20,224 |
| Change vs. Last Year | −9.42% |
Prices have softened 9.42% compared to this time last year, making it a favorable time to shop this model year.
There are 2,525 listings available, which suggests solid inventory for comparison shopping.
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 repeatedly praise its stylish interior, feature set, smooth ride, and fuel efficiency. That makes it a good fit if you want a comfortable compact SUV that leans toward everyday usability and value rather than outright performance. The market also shows 32.0% of listings as good or great deals, which gives you some room to shop selectively.
Is the 2021 GMC Terrain reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
User feedback highlights a dependable-feeling ownership experience, with drivers often describing the Terrain as smooth, efficient, and easy to live with. The recurring praise for comfort and value suggests many owners feel confident keeping it over the long term. For used buyers, that kind of satisfaction can reduce ownership risk, especially if you verify maintenance and condition before you buy.
What should I look for when buying a used 2021 GMC Terrain?
At 74.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should run a vehicle history report on any candidate and confirm whether prior damage was cosmetic or structural. Put inspection priority on body panels, paint match, tire wear, suspension feel, and any warning lights or electronic feature issues. Because the Terrain’s appeal depends heavily on comfort and equipment, focus on overall condition and how well the features work.
Is now a good time to buy a used 2021 GMC Terrain?
This looks like a moderate, selective buyer’s market, so you can be patient and still find a worthwhile listing.
- Deal availability: 32.0% of listings are priced as good or great deals.
- Inventory: There are 2,525 listings available.
- Price trend: Prices have softened 9.42% compared with last year.
- Clean inventory: 74.7% of listings are accident-free.
If you find a listing below $18,320, 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 $18,320 sits slightly below last year's $20,224.
That softer pricing can help you buy at a more favorable entry point, but it also means future resale gains may be more limited if the market stays soft. If you plan to sell later, condition and documentation will matter more because buyers will have plenty of comparable listings to choose from. A well-kept example should still hold appeal thanks to the Terrain’s comfort-focused reputation and broad everyday usefulness.
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:
- 32.0% of listings are priced as good or great deals.
- At 74.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 9.42% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
Consider the 2022 if:
- At $21,792, the 2022 costs more than the current year's $18,320 average.
- It adds an AT4 trim with standard all-wheel drive and a more rugged look.
The bottom line: If you want the better value, the 2021 is the stronger starting point because it combines lower pricing with strong owner satisfaction. If you’re willing to pay more for a newer model year and the AT4’s rugged styling, the 2022 is the secondary path to consider. For most price-sensitive buyers, the 2021 makes more sense unless you specifically want the newer year’s added trim appeal.
