How much does the 2023 GMC Terrain cost?

Prices have softened 13.28% compared to this time last year, making it a favourable time to shop this model year.

There are 840 listings available, which suggests you have a decent amount of inventory to compare.

Is the 2023 GMC Terrain a good car?

Yes — the 2023 GMC Terrain earns a 5/5 user rating, which points to strong owner satisfaction. It stands out as a compact SUV that leans into comfort, a roomy cabin and a more premium feel than many rivals, while its distinctive, more angular design gives it a tougher personality than the Chevrolet Equinox. For you, that means a practical small SUV with everyday usability and an upscale-leaning character. The market also shows 32.5% of listings as good or great deals, which gives you some room to shop selectively.

Is the 2023 GMC Terrain reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The 2023 Terrain’s standard equipment and available technology are a strong part of its identity, including Apple CarPlay, Android Auto and a range of safety features such as automatic emergency braking, lane keep assist, lane departure warning and automatic high beams. Its 1.5-litre turbocharged engine and nine-speed automatic are aimed at everyday use rather than hard driving, which fits its comfort-first mission. For used buyers, the main long-term ownership risk is that some interior materials can feel cheap, so condition and maintenance history matter.

Is now a good time to buy a used 2023 GMC Terrain?

It looks like a moderate, selective buyer’s market, so you can shop patiently and still find worthwhile options.

• Deal availability: 32.5% of listings are priced as good or great deals.
• Inventory: There are 840 listings available.
• Price trend: Prices have softened 13.28% compared with last year.

If you find a listing below $27,457 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 $27,461 CAD sits slightly below last year's $31,666 CAD.

That price movement suggests the Terrain has softened enough to give buyers more negotiating room today. For a future seller, it also means you should expect resale value to depend heavily on condition, mileage and how well the vehicle has been maintained. Because the market has already adjusted downward, a clean example bought well now may be easier to move later if you keep it in strong shape.

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:

• 32.5% of listings are priced as good or great deals.
• Price trend: Prices have softened 13.28% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2022 if:

• At $24,490 CAD, the 2022 costs less than the current year's $27,461 CAD average.
• It adds an AT4 trim with a more rugged look.

The bottom line: Choose the 2023 if you want the stronger overall market position, better deal availability and the more current used-shopping target. If your priority is spending less upfront, the 2022 is the better value play, especially if you like its added rugged styling.
