## Why it stands out
The 2018 GMC Terrain distinguishes itself with a fresh design that aims to appeal to a broader audience while maintaining GMC's "Professional Grade" branding. Unlike its predecessor, the Terrain has shifted from bold and boxy aesthetics to a more conservative and modern profile. This model year offers a choice of three turbocharged engines—including a powerful 2.0-liter option—and two drivetrains (FWD and AWD), providing versatility for different driving needs. Owners appreciate the Terrain's comfort, spaciousness, and variety of features, particularly in higher trim levels. However, some critics point to issues like sensitivity in brake response, occasionally lacking power under certain conditions, and concerns regarding its pricing strategy, which some find questionable against rivals.

4.6 Overall rating
(37 reviews)Awesome car very spacious for a tall guy like me 6”10 definitely would recommend
The features are very good, the value is some what okay. I think its a good vehicle
I went from the Pontiac torrent which I loved to the GMC terrain drives amazing. I love it so far and would recommend to anyone looking to buy a suv.
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!!!!
