CarGurus Analysis: 2018 GMC Terrain
overall
Summary
With 1,934 currently listed for sale and an average price of $14,789.00, 32.1% 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.
63.0% of 2018 Terrain models on CarGurus are accident free.
The 2018 GMC Terrain features a redesigned interior with improved materials, multiple engine options, and cargo capacity of up to 63.3 cubic feet.
Why it stands out
The 2018 GMC Terrain marks a significant redesign from its previous model, shifting from a rugged exterior to a more conservative and streamlined look. Although this change may not appeal to all, it does enhance interior comfort with improved materials and a more organized layout. The Terrain offers multiple engines, including a well-received turbocharged 2.0-liter option that provides a satisfying 252 horsepower and a respectable driving experience. However, it faces criticism for its underwhelming crash test ratings and higher pricing that may deter budget-conscious buyers who could find better options within the compact SUV segment. While the Terrain's cargo space and tech features like Apple CarPlay and Android Auto are beneficial, its overall value compared to competitors like the Honda CR-V leaves some room for concern.

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.
