Why it stands out
The 2018 GMC Terrain attempts to appeal to buyers looking for a compact crossover with a spacious interior and modern technology. It features a smooth driving experience, particularly when equipped with the upgraded turbocharged 2.0-liter engine that delivers robust performance. However, it has received mixed reviews, with many owners appreciating its comfort and variety of features, especially in higher trims. On the other hand, some users have expressed concerns regarding brake sensitivity, inadequate power in specific scenarios, and overall value for money. The 2018 redesign has led to a softer appearance compared to its predecessors, which may not resonate with all former fans of its bold, boxy design. Additionally, while the cabin has been improved with better material quality and functionality, certain pricing issues significantly affect its competitiveness within the market.

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.
