Very nice interior. Excellent options. We went with a black on black model but would have purchased this one if the other had not been available.

I absolutely adore my Terrain! I love everything about it. Not too big, not too small. Zero complaints. If I did have to make a suggestion I would say blind spot protection, and maybe a bigger screen that shows your speed but not deal breakers and simply just suggestions :)

I love the Terrain! It drives great and has a smoothest ride. It also is good on gas.
