excellent service
It was a great experience. Friendly and knowledgeable salesman. The wait time was reasonable. My overall experience there was great
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 Experience
I wanted to purchase a new vehicle. The vehicle I seen online I thought was a great car, Mr. Joel Lisman found me a even better car with less miles and cheaper then the car I was looking at. Once I came to pick up the vehicle I was at Carmax for less than an hour, then I was driving away in my new car. 😁
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.

Great Experience
Terri Anistead was a warm, professional and wonderful salesman. I was impressed with the no mess no fuss flow of the overall process. I was able to say what I want to put down, what price range I want to stay in. Terri followed my ques and not the other way around. What a pleasure. I had a family member go through drive time and I was not sure if it was a good choice. I can see why they picked Drive Time. Thumbs up!
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.

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.

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.

Great experience, surprised with customer service
I am buying a used car after 8 years, and this was great experience. No haggle is what I care. I was not forced to buy GAP insurance or anything else. The only complaint is, the lady taking down payment at the cashier was hesitant to tell me the details of the transactions before making a payment and showing attitude, but everyone else was great. I highly recommend this carmax.

If my credit was on point I would've been driving my dream car. The K900 is a sleeper for those who do not know. But they did try to help.
