overall
Summary
With 1,911 currently listed for sale and an average price of $14,526.00, 30.6% of 2018 GMC Terrains for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 GMC Terrain 4.71 / 5 stars.
62.0% of 2018 Terrain models on CarGurus are accident free.
The 2018 GMC Terrain features a redesigned exterior, improved interior quality, and offers multiple engine options, including a powerful turbocharged 2.0-liter engine.
Why it stands out
The 2018 GMC Terrain stands out with its bold redesign, moving away from the boxy look of its predecessor to a more streamlined appearance. While this new design may appeal to some, it has drawn criticism for losing the rugged aesthetic that once set it apart. The Terrain offers a variety of engine choices, including a turbocharged 2.0-liter engine that delivers a robust 252 horsepower, making it a more engaging drive compared to the base 1.5-liter engine. Inside, the Terrain boasts a spacious cabin with improved materials and a user-friendly infotainment system featuring Apple CarPlay and Android Auto. However, some owners have expressed concerns about brake sensitivity and the overall value proposition, especially when compared to competitors like the Honda CR-V, which offers more cargo space and better safety ratings. Despite these drawbacks, the Terrain remains a solid choice for those seeking a comfortable and feature-rich compact 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!!!!

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.
