Why it stands out
The 2018 GMC Terrain brings a redesigned exterior and an updated interior compared to its predecessors, aiming to cater to modern tastes. Notably, this crossover offers a choice of three turbocharged engines, including a strong 2.0-liter option that boosts its performance appeal. The Terrain also highlights its comfortable seating and spaciousness, making it family-friendly. However, challenges arise with concerns over brake sensitivity and a perceived lack of power in certain driving conditions. Despite these limitations, the Terrain stands out in its segment for its upscale feel, particularly in higher trim levels, and the introduction of advanced tech features. Yet, it struggles to compete on value against rivals, prompting buyers to weigh its strengths against its cost.

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.
