How much does the 2017 GMC Terrain cost?

Prices have softened 4.86% compared to this time last year, making it a favorable time to shop this model year.

There are 1,390 listings available, which gives you a solid amount of inventory to compare.

Is the 2017 GMC Terrain a good car?

Generally — the 2017 GMC Terrain earns a 4.33/5 user rating, which points to strong owner satisfaction. Owners repeatedly praise its comfortable ride, spacious interior, quiet cabin, and attractive design, and those strengths line up well if you want a compact SUV that feels more polished and easy to live with. It is especially appealing if you value everyday usability over quick acceleration, since the Terrain is aimed more at comfort and practicality than performance. With 28.9% of listings marked as good or great deals, you still have room to shop selectively.

Is the 2017 GMC Terrain reliable?

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

The owner feedback also emphasizes dependable everyday comfort, with repeated praise for the quiet cabin, smooth handling, and trouble-free usability. That kind of consistent satisfaction matters if you want a used SUV you can count on for routine driving rather than one that feels demanding to own. For used buyers, the main long-term risk is choosing a poorly maintained example, so condition and service history should carry real weight.

What should I look for when buying a used 2017 GMC Terrain?

At 62.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can separate clean examples from ones with prior damage. After that, prioritize a thorough inspection of body panels, alignment, and signs of uneven wear, since condition can vary meaningfully from one listing to another. Focus on the overall state of the cabin, drivetrain behavior, and maintenance records so you can avoid paying strong money for a tired example.

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

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

• Deal availability: 28.9% of listings are priced as good or great deals.
• Inventory: There are 1,390 listings available.
• Price trend: Prices have softened 4.86% compared with last year.
• Clean inventory: 62.8% of listings are accident-free.

If you find a listing below $11,029, 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 $11,142 sits slightly below last year's $11,711.

That softer pricing suggests the Terrain has become easier to buy than it was a year ago, but it also means future sellers may face some pressure if the market stays loose. If you buy well and keep the vehicle in strong condition, you can help protect your exit value. The model’s steady owner satisfaction should also help support demand when it is time to sell.

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?

If you're weighing the 2017 against nearby model years, here's how to think about it:

Choose the 2017 if:

• 28.9% of listings are priced as good or great deals.
• At 62.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 4.86% compared with last year.
• Owners rate it 4.33/5 — a solid satisfaction signal.

Consider the 2018 if:

• At $14,061, the 2018 costs more than the current year's $11,142 average.
• It brings a redesigned look that changes the Terrain’s styling and overall presentation.

The bottom line: If you want the better value play, the 2017 is the stronger starting point because it combines lower pricing with solid owner satisfaction. If you are willing to spend more for a newer model year, the 2018 is the alternative to compare, but price-sensitive buyers will likely find the 2017 easier to justify.
