Summary
With 141 currently listed for sale and an average price of $21,045, 36.2% 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.

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.

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 | $17,919 |
| Year-Round Low | $17,919 |
| Year-Round High | $20,057 |
| Average Price a Year Ago | $20,056 |
| Change vs. Last Year | −10.66% |
Prices have softened 10.66% compared to this time last year, making it a favorable time to shop this model year.
There are 2,437 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 consistently praise its stylish interior, feature set, smooth ride, and fuel efficiency. That fits well if you want a compact SUV that feels more polished and upscale than many rivals, especially for everyday driving. With 31.4% of listings marked as good or great deals, you also have a decent chance of finding attractive pricing.
Is the 2021 GMC Terrain reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The user feedback also points to a dependable, trouble-free ownership experience, with owners highlighting the Terrain’s overall value and comfort over time. That kind of response suggests the model has earned trust from people living with it day to day. For used buyers, the main long-term risk is less about reputation and more about finding a well-kept example with clean history and consistent maintenance.
What should I look for when buying a used 2021 GMC Terrain?
At 74.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should run a vehicle history report before you commit, then prioritize a pre-purchase inspection on any listing that looks especially appealing. Focus on condition details that matter most on a used compact SUV: signs of prior bodywork, interior wear, tire and brake condition, and whether all tech features work as expected. If a listing has a strong price but a questionable history, make sure the discount is enough to justify the added risk.
Is now a good time to buy a used 2021 GMC Terrain?
This is a moderate, selective buyer’s market, so you can shop with some leverage if you stay disciplined.
- Deal availability: 31.4% of listings are priced as good or great deals.
- Inventory: There are 2,437 listings available.
- Price trend: Prices have softened 10.66% compared with last year.
- Clean inventory: 74.9% of listings are accident-free.
If you find a listing below $17,919, 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 $17,919 sits slightly below last year's $20,056.
That softer pricing can help you buy in at a more favorable point, but it also means future resale gains may be limited if the market stays soft. If you plan to sell later, your best protection is choosing a clean, well-maintained example with strong documentation and avoiding vehicles with accident history. A lower entry price can help offset depreciation, especially if you buy near the bottom of the range.
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:
- 31.4% of listings are priced as good or great deals.
- At 74.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 10.66% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
Consider the 2022 if:
- At $21,183, the 2022 costs more than the current year's $17,919 average.
- It adds an AT4 trim with standard all-wheel drive and a more rugged appearance.
The bottom line:
Choose the 2021 if you want the better value and are comfortable shopping carefully for condition and history. If you want a newer model with a more rugged trim and can stretch your budget, the 2022 is the secondary path to consider.
