Is the 2017 GMC Terrain a good car?

Generally — 4.33/5 is a strong user rating for this model year. Owners commonly praise the comfortable ride, spacious interior, quiet cabin, and attractive design, and those strengths make sense if you want a compact SUV that leans more toward comfort and practicality than flash.

Is the 2017 GMC Terrain reliable?

Owners rate it 4.33/5, a solid signal of long-term satisfaction.

The owner feedback points to a vehicle that many drivers find comfortable and dependable in day-to-day use, with a quiet cabin and smooth handling contributing to that positive impression. The strongest version to seek out is the one with the 3.6-litre V6, which is described as the only first-generation engine not known for significant reliability issues. For used buyers, the main long-term ownership risk is ending up with a less desirable engine configuration, so careful shopping matters.

Is now a good time to buy a used 2017 GMC Terrain?

This looks like a moderate, selective buyer’s market, so you can afford to be patient and compare listings.

• Deal availability: 23.0% of listings are priced as good or great deals.
• Inventory: There are 148 listings available.
• Price trend: Prices have softened 13.71% compared with last year.

If you find a listing below $12,247 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2017 GMC Terrain's resale value?

The current average of $12,699 CAD sits slightly below last year's $14,717 CAD.

That price movement suggests the market has already adjusted downward, which can make this a more approachable used buy today but may also limit upside if you plan to resell soon. If you buy at the right price, you reduce the risk of taking a bigger depreciation hit later. The Terrain’s comfort-focused appeal should help it stay relevant with shoppers who want a practical compact SUV rather than a sportier alternative.

Vehicles with solid owner satisfaction ratings, like this model year's 4.33/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2017 GMC Terrain or consider a different year?
