CarGurus Analysis: 2023 GMC Terrain

Summary
With 163 currently listed for sale near Mississauga, ON and an average price of $25,718 CAD, 36.2% of 2023 GMC Terrains for sale on CarGurus are rated as good or great deals.
Favourably reviewed: Owners rated the 2023 GMC Terrain 5 / 5 stars.
100.0% of 2023 Terrain models on CarGurus are accident free.
Why it stands out
The 2023 GMC Terrain stands out as a compact SUV that leans into comfort, a roomy cabin and strong safety equipment rather than outright space or performance. It also benefits from the Terrain’s more angular styling, which gives it a tougher look than some rivals, and from the model’s generally attractive used-car pricing. For shoppers who want a premium-feeling small SUV without moving up to a larger vehicle, that combination is a big part of its appeal.
For 2023, the Terrain carried over the second-generation formula with a 1.5-litre turbocharged engine, a nine-speed automatic and standard Apple CarPlay and Android Auto. GMC also made important safety technology standard for this generation, including automatic emergency braking, forward collision alert with pedestrian detection, lane keep assist, lane departure warning and automatic high beams. The 2023 model also had an upgraded trailer braking feature, though it did not increase towing capacity. Buyers could still appreciate the Terrain’s available features such as an eight-inch touchscreen on many models, while the cabin’s push-button gear selector and better sound insulation helped reinforce its more upscale positioning.
There are trade-offs, though. The Terrain’s cargo area is smaller than that of top rivals, and some interior materials feel cheap. Performance-minded buyers may also find the 1.5-litre engine adequate rather than exciting, especially since the more powerful 2.0-litre option was no longer part of the lineup by this point. Even so, the 2023 GMC Terrain remains appealing for shoppers who value a comfortable ride, a well-equipped interior and a used SUV that can be easier on the budget than some of its best-selling competitors.

- Deal availability: 33.2% of listings are priced as good or great deals.
- Inventory: There are 855 listings available.
- Price trend: Prices have softened 12.98% compared with last year.
If you find a listing below $27,453 CAD, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2023 GMC Terrain's resale value?
The current average of $27,731 CAD sits slightly below last year's $31,866 CAD.
That price movement suggests the Terrain has become more accessible on the used market, which can help you buy at a better entry point today. For a future seller, the softer pricing means resale gains may be more limited unless the vehicle is especially well kept and well equipped. If market conditions stay steady, the Terrain’s value should be supported by its comfort-first appeal and broad shopper interest.
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 2023 GMC Terrain or consider a different year?
If you're weighing the 2023 against nearby model years, here's how to think about it:
Choose the 2023 if:
- 33.2% of listings are priced as good or great deals.
- Price trend: Prices have softened 12.98% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
Consider the 2022 if:
- At $24,663 CAD, the 2022 costs less than the current year's $27,731 CAD average.
- It adds a rugged-looking AT4 trim with standard all-wheel drive.
The bottom line: Choose the 2023 if you want the better-balanced used buy, especially with softer pricing and strong owner satisfaction. If your priority is spending less upfront, the 2022 is the better secondary path, particularly if you like its more rugged styling and lower entry price.
