Cody, my salesman, was professional, helpful, honest, and a pleasure to work with. There was no pressure at any point during the process. JP, the sales manager, was also easygoing and pleasant to work with. They were both very accommodating in negotiating a fair price—They even allowed me to inspect the underside of the vehicle, which I really appreciated.
Bought the car CPO in summer 2021 with 38k miles.
Bought the car CPO in summer 2021 with 38k miles. Now being summer 2024 with 90k miles and I’ve mostly had good luck with the car and its components. I have the extended warranty through 100k miles but I feel like all American cars are built to fail after the warranty runs out. Overall great car: I have the 2.0L turbo engine with 9 speed auto and AWD. AWD is great when turned on, grips the road well, and to be honest the 2.0L has a TON of power; way more than you need for a compact SUV! I had a quick issue around 65k miles where the service traction control and stability light came on for 15 minutes. Dismissed itself and haven’t had an issue since. At 75k miles, it was during the winter time, the car would display “park break realized” and “service traction control” when the auto start stop would kick back on (there’s no way to shut off the auto start/stop system). No issues and lights but the messages would pop up and dismiss themselves. Little did I know it was my battery dying and my mechanic said “some wires were loose” and he tightened them up. Haven't had an issue since I got a new battery. Last thing that happens is sometimes when you have Apple CarPlay going and you unplug the phone, the infotainment system will freeze and no Bluetooth, usb, or CarPlay will work for the reming duration of the ride unless you stop the car and let it sit for at least 30 minutes. Simply shutting it off and turning it back on never worked. Overall I give this car a good rating for 0-100k miles. I am pleased with the car but looking for something bigger soon. I think I did overpay a bit for it ($30k for 38k miles) since I got it summer of 2021 when new cars were nonexistent!

We worked with Steve who was our salesman. Steve was a genuine, honest, lovely man who just want it to make us happy. He didn’t push anything. He was thorough, helpful, and I felt as though we were treated with respect and kindness and honesty.
Gas and diesel terrain
I have owned 5 of the 2018-19 terrains. I have had the 1.5 gas, 2.0 gas and the 1.6 diesel. The power on the 2.0 is awesome. Mileage on the 1.5 is good. Mileage on the 1.6 diesel is great. I have 336,000 miles on my diesel. It has had lots of issues due to emissions and transmissions. Last week it got a new engine as well. The car is a great car but I would recommend the 1.5 gas for most people. The terrain is comfortable and makes a great work or travel vehicle. Size is easy to park with plenty of leg room.

Was a great purchase experience.
Was a great purchase experience. Ashleigh my salesperson was an absolute pleasure to work with. Customer service oriented. She wanted to make you comfortable and happy. Financing was simple and easy to. I recommend looking for your next car purchase here.
My GMC Terrain saved my life.
Great savings on gas and mileage, very reliable and comfortable. Saved my life when I was in a big rig truck accident as driver side and front side bags deployed. I've become a GMC customer for life as I will be looking forward to buying another GMC SUV.

Buying a new car that day was not necessarily my
Buying a new car that day was not necessarily my intention (was lease was up in 2 months & was investigating options). But the conversation progressed in that direction & Anthony my salesman & the dealership were flexible and worked within my budget. Anthony was very pleasant, knowledgeable about the Hybrid model and explained all features and details. Overall it was a satisfying experience and I am delighted with my new car.
We love this automobile.
This is a higher trim model with the bigger 4 cylinder engine (2.0 vs. 1.5) most of the options including Bose sound system. We love our pick and the only reason I gave 4 stars to comfort is the ride. Granted it rides nice, but you only get 5 stars from heavier sedans. Trucks and SUV's just aren't designed for that really smooth ride. Definitely would recommend the 2.0L engine if you tend to pass on a 2 lane road or need to pull out quick in traffic.

My appt was at 8am w/ Gabe, and although very busy?he was polite, patient and informative because I had questions lol. Gabe listened and understood my issue and was very transparent in what could and/or couldn?t be done. He set up an Uber to take me to work and my vehicle was ready by lunch time. Happy Customer ?
Best choice
I love my car thus far. It included every feature plus a couple extras that I was looking for. Of all the cars I’d driven my Terrain Denali was the best choice for me.

Our salesperson Anthony Cruz went above & beyond to try and find the right car for us, he is not that normal pushy sales guy that only cares about his sale then leaves you. He is great at communication, knowledgeable about the vehicles and understanding to the customer. I highly recommend purchasing a car from him!

Great car lot
I love the no hassle car buying experience and my salesman was a good guy that was a veterans car salesman. They took care of getting me set up with a second key very quickly and got me a great interest rate on my loan I quickly paid off within 6 months. I will shop there again and have sent many members of my family there!!
