Why it stands out
The 2018 GMC Terrain is a strong contender in the compact SUV segment, offering a blend of comfort, spaciousness, and a variety of features that appeal to a wide range of buyers. Owners appreciate its smooth driving experience, particularly with the available 2.0L turbo engine, which provides a satisfying balance of power and efficiency. The Terrain's design is more angular compared to its Chevrolet Equinox sibling, giving it a rugged appearance that is well-suited for off-road adventures, especially in the AT4 trim. While it lacks some key components like a hybrid powertrain, the Terrain compensates with a well-appointed interior and advanced safety features, making it a practical choice for families and individuals alike. However, some users have raised concerns about brake sensitivity and power delivery in certain situations, which potential buyers should consider.

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.
