Why it stands out
The 2018 GMC Terrain stands out for its bold redesign and updated features, appealing to buyers looking for a compact crossover SUV that combines style with practicality. Notable features include its variety of engine choices, particularly the turbocharged 2.0-liter engine that provides a powerful performance compared to its competitors. The Terrain also boasts a well-equipped interior with modern infotainment technology, including a user-friendly system with Apple CarPlay and Android Auto. However, it faces criticism for not meeting safety expectations, with a mediocre crash-test rating that may deter safety-conscious families. Despite the spacious cabin and cargo area, some buyers may find better value and features in competing models, leaving the Terrain's overall appeal somewhat diminished.

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.
