overall
Summary
With 89 currently listed for sale near Denver, CO and an average price of $30,000.00, 21.3% 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.
87.6% 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 modern and streamlined appearance. While this new design may appeal to some, it has received mixed reviews regarding its aesthetic compared to competitors. The Terrain offers a spacious interior with a variety of features, particularly in higher trim levels, making it a comfortable choice for families. The availability of multiple engine options, including a turbocharged 2.0-liter that delivers 252 horsepower, enhances its performance, especially for those seeking a more dynamic driving experience. However, some users have expressed concerns about the vehicle's brake sensitivity and overall power in certain situations. Additionally, the Terrain's value proposition is questioned due to its pricing, which can be high compared to rivals that offer more features and better safety ratings.

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.
