Mario was very enthusiastic and willing to help in my search for the right vehicle.
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!

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.

Kelsey was at lunch when I've arrived but was smiles and asked about my service(s) my car was due for. Just an Oil change was needed, she did an overall maintenance check up on the computer since my last visit. Told me about the conditions of Wiper blades & tires, since we are going into early fall season. I appreciated that. Teresa had the day off, Kelsey stepped up and filled some big shoes, Thank you Kelsey for listening to me and telling me what's due in the coming maintenance mile marker chart. I'm very happy customer doing business with Serra Kia as of 9/02/2025
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.

Extremely well run and efficient car dealership.
The twins run a great used car dealership. Very professional. Purchased a Tahoe from them yesterday (while I have not yet received the registration and title), these guys are really nice and top-notch. Mark is a great salesman as well. The experience was excellent. Thanks, guys. I will be back for future car purchases.

My family and I recently purchased a Chrysler minivan
My family and I recently purchased a Chrysler minivan from Twins Auto, and the experience was excellent from start to finish. Allen guided us through the entire process, handling both the sale and financing with professionalism and patience. He answered all of my questions thoroughly and made sure I understood every step. The APR rate I received was outstanding, and the vehicle was spotless upon delivery. Overall, the entire experience was smooth, transparent, and hassle-free. I highly recommend Twins Auto for anyone looking to buy a vehicle!

Happy
We were looking at a variety of used vehicles and found nothing but very high prices on very high mileage cars. I was hesitant at first but as with everything....do the footwork. We were never followed, pushed or hounded, all the members of Zains team were helpful and up front about their vehicles, even so much as to steer me away from one I was looking at. I was allowed to take the vehicle to my mechanic and have him go over it which he did...and he told me to go do the deal. I showed him the pre-repair pics so he knew where to dig....i drove the car about an hour and put it thru a workout. One can NEVER be cautious enough so do your work. This is why sites like Carfax can be your friend. If you do a vin search you can see the Pre-repair damage, this is crucial for your mechanic. My experience: I feel secure with our 2017 GMC and would like to thank the Brokers and Sellers team for their refreshing attitude with all my questions.

Finding value in a used automobile is difficult, but Moe
Finding value in a used automobile is difficult, but Moe at Car Dome Auto Sales ensured I got the most bang for my buck. After discussing my budget and requirements, Moe showed me cars with the best characteristics for the money. I didn't feel like I had to sacrifice quality to keep inside my budget. The entire process felt honest and fair, and I drove away feeling I had received a wonderful price.

I worked with Omar and he did a great job during the entire process from picking me up at the airport to going over the technical issues with the AMG SL that I purchased. The paperwork was done in a matter of minutes as he had everything organized. He spent as much time as necessary getting me out the door for my enjoyable ride home to Memphis. Hats off to the Roadrunner Team that supported him as well.
