AMAZING DEALERSHIP AND PEOPLE
Honestly the BEST car buying experience we have ever had:) I highly recommend Gay Family Auto Trey, Kiss and Steve are amazing. From the time we walked in to the day that Trey delivered my sons truck it was ABSOLUTELY PROFESSIONAL.
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!

Excellent service
Laurence was very professional and he got me in the car of my choice in less time. he addressed my concerns. Even though they were undergoing construction. All the sales men/women were smiling as they said hi to me.
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.

Kyle and his team did amazing as we have come to expect. This visit was for new tires. Blessed to have this team to service our vehicles.
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.

The environment is good, the service is good, too. The service staff introduce the car in detail patiently and warm-heartedly. I am very happy with his service.
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.

Great simple oroceds
Rees was my greeter and was an excellent source of information and sales expediter. Rees explained the CarMax process and then Listened to the car features I required. He did searches of car max inventory, searches of manufacturers’ sites for additional info, and requested transfer of a vehicle from another location. There was no pressure to buy (CarMax has a five day return policy). Paperwork was efficient, and I even got help getting both the car I bought and the car I arrived in home. It was my first solo car buying experience so I especially appreciated that I got a car that suited me at a fair price and no hassle
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.

Made sure it was good "car max" car.
We purchased a fleet vehicle that had some ac issues and transmission problems. Carmax jumped right into correcting the issues and provided a rental car each time. I will definitely purchase from here again.

2017 Honda Civic
I bought a 2017 Honda Civic last week. I was preapproved before I walked into the dealership. There were a couple of issues once I began completing the buying process, but after 3 hours at the dealership, I walked out with my new vehicle.
