With 1,927 currently listed for sale and an average price of $14,449.00, 32.5% of 2018 GMC Terrains for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 GMC Terrain 4.71 / 5 stars and CarGurus experts gave it a 6.17 / 10.

Why it stands out
The 2018 GMC Terrain arrives with a conservatively redesigned look, but its appeal is undercut by the fact that it no longer has the rugged styling that once helped it stand out. It is a conceptually appealing compact crossover SUV, yet the overall impression is that it falls apart under scrutiny. The vehicle also does not meet safety expectations for a brand-new design, which makes it harder to recommend.
Even so, owners often describe the 2018 Terrain as comfortable and spacious, with a good variety of features available, especially in higher trim levels. Many also found it smooth and enjoyable to drive, particularly with the 2.0L turbo engine. At the same time, some reviewers raised concerns about brake sensitivity, a lack of power in certain situations, and pricing issues, which reinforces the sense that its strengths are balanced by notable drawbacks.

It’s the Denali so it has everything you need plus more. Only thing that would make it better would be a V6 but this 2.0 turbo has major get up and go.

The car is amazing and of great value. We purchased this vehicle for under the market value and it is in excellent condition. I did a thorough walk around and probably looked like an idiot looking for the smallest dents and scratches. The vehicle has great options, panoramic roof and good quality materials, especially for the price. What a steal my wife got!!!!

This car exceeded my highest expectations. Very nice ride, appropriate amount of room and has a very sporty feel. Has a lot of extra features that make it over all a very nice care. The push gear buttons will take some time to get use to but over all very very cool.

I like the car, but the brakes are a little sensitive and the pick-up (from a stop) can be jerky. Otherwise, it is smooth, comfortable, and a quiet ride.
