CarGurus Analysis: 2018 GMC Terrain
overall
Summary
With 1,966 currently listed for sale and an average price of $14,643.00, 35.5% 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.
63.9% of 2018 Terrain models on CarGurus are accident free.
The 2018 GMC Terrain features a redesigned exterior, improved interior materials, and offers a choice of three turbocharged engines, including a powerful 2.0-liter option.
Why it stands out
The 2018 GMC Terrain stands out with its bold redesign, moving away from the boxy styling of its predecessor to a more streamlined appearance. While this new look may appeal to some, it has drawn criticism for losing the rugged charm that once defined the Terrain. Inside, the Terrain boasts a more refined interior with improved materials and a user-friendly control layout, although some may find the quality lacking for its price point. The vehicle offers a variety of engine options, including a robust 2.0-liter turbocharged engine that enhances performance significantly compared to the base model. However, the Terrain's safety ratings have raised concerns, particularly with a mediocre 3-star rating for rear seat side-impact protection. Overall, while the Terrain offers comfort and a spacious interior, potential buyers should weigh its strengths against its limitations, especially regarding safety and value compared to competitors.

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.
