Why it stands out
The 2018 GMC Terrain is a compact crossover that aims to appeal through its blend of comfort and spaciousness. It offers a variety of features across its four trim levels, which include options like front-wheel and all-wheel drive, and engines varying from a fuel-efficient turbocharged 1.5-liter to a more powerful 2.0-liter option. Despite these strengths, its new design has sparked some controversy, losing the rugged appeal of earlier models in favor of a softer aesthetic. While it features a well-thought-out interior with modern tech integrations, critical reviews point out the lack of safety features compared to competitors and a mediocre safety rating, which might concern families. Handling is commendable, along with a comfortable ride, but some drawbacks like stiff steering and brake sensitivity have been noted. Overall, while the Terrain is inviting with its spacious interior and engine options, potential buyers should weigh its varied strengths against its more significant limitations.

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.
