Why it stands out
The 2018 GMC Terrain distinguishes itself with a fresh redesign that aims to appeal to a broader audience while maintaining its compact SUV status. While the new look is more conservative compared to its predecessor, it offers a spacious interior and a variety of features, particularly in higher trim levels. The availability of three different engines, including a robust turbocharged 2.0-liter option, provides buyers with choices that cater to their performance needs. However, some reviewers have expressed concerns regarding the vehicle's brake sensitivity and overall power in certain driving situations. Despite these limitations, the Terrain remains a comfortable and enjoyable vehicle to drive, especially with its smooth ride and user-friendly technology features.

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.
