I can say I enjoyed buying a car from Covert.
I can say I enjoyed buying a car from Covert. Starting with Jud, every person made me feel more than just a customer buying a car. Each staffer showed genuine interest in me getting what I wanted. I wasn't just a commission or one step closer to meeting the monthly sales goals. And, that is the best reason to buy a car from you. So, thank you.
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

My experience could not have been better.
My experience could not have been better. Terrie was our sales rep and she was FANTASTIC. She made me feel like I was only sale for the day. She took the time to explain anything I didn’t understand. Took us on a great tour of Beaver also. I don’t think I would have bought my Tacoma from anyone but Terrie. Thank you.
Amazing SUV
I’ve had an amazing experience with terrain Denali. I had it for 3 years and it was one of the best cars ever. Everything worked perfectly no issued at all! Loved it

I could not have asked for a better service experience.
I could not have asked for a better service experience. I was so frustrated when I brought my car in because another dealership had quoted me 6-8 weeks to fix a simple issue. Matt in the body shop told me he'd have it for two weeks and would ensure everything was covered under warranty. Not only that - they were done a week early! I received daily phone call updates and was so impressed by the level of care given.
Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

I just purchased a car from Currie Chevy and had an outstanding experience! Miguel gave me a great price and an amazing deal. He went above and beyond to help me find the perfect vehicle, truly listening and understanding my situation while working tirelessly to make it happen for both me and my husband. His professionalism, honesty, and dedication made the entire process smooth and stress-free. If you’re in the market for a new car, I highly recommend visiting Currie Chevy and asking for Miguel—you’ll be in great hands!
