Why it stands out
The 2018 GMC Terrain attempts to deliver a blend of style and functionality, though it has faced criticism for diverging from the rugged image that previously distinguished it in the compact SUV market. This redesign offers a smoother and more refined look, although some buyers may find the lack of the previous boldness disappointing. Performance-wise, the option of a turbocharged 2.0-liter engine offers a notable increase in power, making it the preferable choice compared to the 1.5-liter engine, which has been deemed "adequate" by reviewers. In terms of technology, the Terrain comes equipped with GMC's latest IntelliLink system that includes essential features like Apple CarPlay, Android Auto, and an available Wi-Fi hotspot, aiming for a modern driving experience. However, buyers should consider its mixed safety ratings from federal crash tests, which may deter those prioritizing family safety in their vehicle choice.

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.
