Why it stands out
The 2018 GMC Terrain presents a significant redesign that aims to appeal to a broader audience, moving away from its previously bold and boxy styling to a more conservative look. While the new design may attract some buyers, it has received mixed reviews regarding its overall execution. The Terrain offers a choice of three engines, including a turbocharged 2.0-liter option that provides a more satisfying driving experience compared to the base engine. However, the Terrain's interior quality and cargo space have been criticized, especially when compared to competitors like the Honda CR-V. Despite these drawbacks, the Terrain is appreciated for its comfort, spaciousness, and a variety of features, particularly in higher trim levels. The vehicle's performance is generally commendable, but some users have noted issues with brake sensitivity and power in certain situations. Overall, the 2018 GMC Terrain is a solid choice for those seeking a compact crossover, but potential buyers should weigh its strengths against its 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.
