overall
Summary
With 1,914 currently listed for sale and an average price of $14,817.00, 32.7% 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.
64.1% of 2018 Terrain models on CarGurus are accident free.
The 2018 GMC Terrain features a redesigned, more conservatively styled appearance, multiple engine options, and improved interior amenities.
Why it stands out
The 2018 GMC Terrain represents an evolution in both styling and functionality for GMC's compact crossover SUV lineup. This model boasts a completely redesigned exterior that, while softer and more subdued than its predecessor, meets modern tastes while still aiming to appeal to a broad audience. Under the hood, the Terrain offers multiple engine options including a responsive 2.0-liter turbocharged engine, providing a commendable 252 horsepower, which enhances the driving experience. Despite its redesign, some owners express concerns about performance nuances, such as brake sensitivity and power delivery in certain situations. The vehicle's interior, now with a focus on quality and functionality, includes an 8-inch touchscreen with updated IntelliLink technology, promoting smartphone integration through Apple CarPlay and Android Auto. However, critiques regarding its overall value proposition compared to competitors like the Honda CR-V are noteworthy, especially considering safety ratings and interior material quality.

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.
