What Our Members Are Saying about the Seat Room and Comfort of the 2015 GMC Terrain
| 2015 GMC Terrain Seat Room and Comfort: Pros | ||
| Year | Body/Powertrain | Comment |
| 2015 | 4dr SUV 301-horsepower 3.6L V6 6-speed shiftable automatic AWD |
The rear seat room is plentiful, and because rear seat can be slid forward and back, you can shift between needing more leg room and using more of the cargo area. We had traded in a 2015 Dodge Journey for the Terrain, because of safety concerns, but realized after we had it for awhile, the rear seat of the Journey was not able to go back far enough into the cargo area, and because of the bulky and high mounted head rests, you felt trapped. The Terrain does not have these issues and feels much more roomy and comfortable. The rear seats are supportive and not at all like some back seats that feel like they were an afterthought. see full GMC Terrain review |
