Jesus, who handles the internet request, was prompt to respond to my inquiry, and was waiting for me when I arrived at the dealership. Answered all my questions, very professional, helpful and yet friendly.
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!

Went in for oil change.
Went in for oil change. Got in right away. Out within an hour. Customer Service was great. Facilities very clean. Overall was a great experience.
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.

Our car buying experience with Classic Buick was great!
Our car buying experience with Classic Buick was great! If you're shopping for a new car, go check them out. And ask for Alejandro Serrato! He made everything go smoothly. Definitely worth the drive to work with him!
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.

Found the exact Mustang GT I was looking for at
Found the exact Mustang GT I was looking for at AutoNation Ford and reached out to the online Chat Person. They referred me to Christian Rodriquez and from there his attentiveness and ability to answer all my questions by text message had me sold on buying from the dealership. He was honest and upfront about price, etc. And unlike a salesman I had dealt with at another Metroplex Dealership, he was well versed in both the car he was selling and seemed to really want to sell the car. The dealership overall did a great job with the sales process and had the car ready for me when we drove up to buy it (even thought we hadn't committed to buying it / debating a different color). If you are looking to buy a Ford, reach out to Christian and the others at AutoNation in Ft. Worth.
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.

We were looking for a particular year and model of car
We were looking for a particular year and model of car for our business and found one here at Gordon Chevrolet. An online inquiry was answered by Ryan from their used car department. Ryan was prompt, professional and very consistent in the company’s messaging related to the vehicle and the integrity of their organization. The sale process went very smoothly and the digital automation of the document process was exceptional. Every staff member was courteous, professional and knowledgeable and I recommend them highly based on this experience.

Service Department is outstanding.
Service Department is outstanding. I was traveling alone from Fort Worth to Houston and thought I needed a new battery. The service department checked everything 5 times, showed me how to reset everything, and got me off on my way in less than an hour at no charge. Such patience and concern!

I had an excellent experience purchasing my new truck,
I had an excellent experience purchasing my new truck, and a huge part of that was thanks to my salesperson, Pedro. From start to finish, Pedro was professional, knowledgeable, and genuinely focused on making sure I was comfortable and confident with my purchase. He took the time to answer all my questions, was transparent throughout the process, and never made me feel pressured. The entire experience was smooth, stress-free, and actually enjoyable—something you don’t always hear when it comes to buying a vehicle. If you’re in the market for a new truck and want someone who truly cares about customer service, ask for Pedro. I highly recommend this dealership and would absolutely come back again.

The customer service, the compassion and understanding
The customer service, the compassion and understanding were truly great. Suzanne and Jason were incredibly kind, very responsive and explanatory and provided us with all around amazing service. We were contacted quickly after our online inquiry and Suzanne was happy to help us answer all the questions we had. We are out of state and the process in which the paperwork and transport of the vehicles were done was flawless. We thank you all for your expertise and kindness. We will be back when the time comes and will most certainly refer all who are in the market to your dealership.

Yes , even if I drive over 20 miles away from Toyota
Yes , even if I drive over 20 miles away from Toyota automation in Weston I love and trust the quality of service . Your service team from the service advisors to the mechanics is fantastic . But today I like to express my special thanks to Andre for all the support he provided, he is very professional and thorough. I was very impress with his way to explain the service options I had. And went out of his way to keep me well informed of surprises found during the service helped me get a loaner for extended time and call me to let me know the car was ready. There are no words to express how please I am with my interactions with Andre. He is a True example of AutoNation Toyota commitment to customer satisfaction. Thank you Andre
