Covert Buick GMC Austin review
Upon arriving at the Covert Buick dealership, I was
Upon arriving at the Covert Buick dealership, I was greeted by Beto. He was helpful, and willing to spend as much time as I needed. All of my concerns and questions were answered. I was very impressed with him. In fact, everyone that was involved in the buying process was wonderful. Charlie, that completed the buying process, was so personable and made it all painless!
2025 GMC Sierra 2500 Denali review
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.
