Smooth buying process, reliable service.
Smooth buying process, reliable service. Only issue is not being able to get in and out for routine maintenance or repair issues.
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.

Great experience.
Great experience. Jay Rector was very helpful. Low pressure. Did not have exactly what we wanted. He did not try to sell on what he had. He let us decide and order.

My salesman, Dexter Arnold, was very nice and helpful. It was a pleasure dealing with him. He seems to genuinely care rather than just trying to make a sale. The finance guy was pretty cool, too.
