The engine has the power we need to tow a trailer with our newest toy!!

Transmission: Automatic Color:Gray Interior Color: Black Average Vehicle Review: (0 reviews) The GMC Terrain is a really stylish and expensive looking vehicle. I have an upgraded interior package but it was still priced just under $20k and believe it was an excellent price and value. The gas mileage on the highway is wonderful, I really do get close to 32 mpg and if I'm driving on longer stretches of in town streets I get in the 20's. Even though it's compact the interior affords tons of space for passengers, animals, luggage and small pieces of furniture. So far I've had no issues with any systems. My only complaint would be that the A/C doesn't seem particularly cold to me and doesn't flow to the back of the car very well but for the most part it's not a problem. I couldn't be happier with this car and hope it lasts.

Even with the third row up, there is still plenty of room for strollers, backpacks, and any other gear you might need. Most third row vehicles only provide a few inches between the third row and back door. But not the Acadia

Transmission: Automatic Color:Black Interior Color: Black Average Vehicle Review: (4 reviews) This car is very comfortable, has a smooth ride and is surprisingly roomy inside. I have a wife and 2 children and we frequently take road trips in excess of 500 miles. We are able to fit the whole family and all our luggage and whatever we need while still fitting comfortably in the cab. We have the SLT2 package so it has memory seat and mirror positions which makes it really easy when switching drivers without having to take too much time to readjust everything. My favorite feature is how the side view mirrors tilt down when backing up, making it remarkably easy to see the lines of a parking spot. The backup camera is also a big plus. Despite all it's room to make it feel like an SUV inside, it's still very compact which makes it easy to

Transmission: Automatic Color:Brown Interior Color: Black Average Vehicle Review: (0 reviews) Incredible engine performance, interior finish and options on the Denali are top notch, great family car and performs very well in Colorado's winter driving conditions. I do miss the manual four wheel drive options of the Tahoe, as this model uses GMC's all wheel drive system. Otherwise, not a single complaint.

Transmission: Automatic Color:Black Interior Color: Black Average Vehicle Review: (0 reviews) I went from a 2012 Camry to this 2013 Acadia. It works for me since I have 3 small children. With the split-bench 2nd row, my 5-year-old can get in and buckle himself. It's very good if I need extra cargo space with letting part of the 3rd row down. But I don't like the car seat latch for the 3rd row. It's in the middle of the seat, which means I have to rigid my 5-year-old's high-back booster seat. But other than that it works for me, for now!

Would Not Recommend a used Denali

I purchased a 2015 GMC Acadia Denali (one owner prior to me owned it for 15 months) and the air conditioning went out two weeks after purchase. After repaired, it went out again two weeks later. A GMC dealership replaced the entire unit! Also, the weather stripping on top of the vehicle detaches after each car wash and flaps independently unless I manually press it securely in position. A GMC dealership informed me this is something that happens and provided no solution to make it more secure. The quality of the vehicle is not Denali (in other words, top of the line).

- Jennifer Moses, 2015 GMC Acadia

Love my car!

It feels secure and it's a comfortable ride. I love the middle captain's chairs because it makes the 3rd row easily accessible and it gives the middle row riders more rooms to relax. The leg room can be a little tight if you have a tall driver, but it's not terrible. Love the heated seats!

- Courtney R, 2013 GMC Acadia

Great touring vehicle

We've had this car for about a year and a half. It's been a very reliable vehicle. Our only trouble with it has been at 60,000 miles the power steering pump went out and we developed a knock in the steering which had us replacing rack and pinion. I don't believe this should be a problem with a vehicle with less than 100K on it, but it was a fleet vehicle before we bought it. I'm not a pro, but I choose to give the vehicle the benefit of the doubt and say that maybe it wasn't cared for as it should have been since it belonged to a fleet. Other than that, the car has been a dream to drive. We've taken it on trips half way across the US, and it's very comfortable. As long as we have no more major problems, I will buy another.

- Nancy, 2011 GMC Acadia
