Why it stands out
The 2018 GMC Terrain stands out for its ambitious redesign, transitioning from a bold and boxy exterior to a more conservative SUV aesthetic. While this change may disappoint some long-time fans, it allows the Terrain to appeal to a broader audience. Its improved interior offers better materials and a more streamlined control layout compared to its predecessor, addressing previous complaints about the cabin quality. Additionally, its variety of engine options—including a robust turbocharged 2.0-liter four-cylinder—provides improved performance for those who seek more power under the hood. Despite these strengths, it falls short in terms of safety ratings and competitive pricing, leaving buyers with more compelling options on 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.
