2025 GMC Sierra 2500 AT4 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.

My sales person at Castle Chevrolet was Tony Twall.
My sales person at Castle Chevrolet was Tony Twall. He was awesome to work with. He answered all my questions and was very knowledgeable. I have to say that this was the best vehicle buying experience I have ever had. My next purchase will be with the Castle dealership in McHenry IL and I will ask for Tony to be my sales person.

Ettleson Buick GMC review
Purchase of a certified Buick Regal
I live far from this dealership but they had exactly what I was looking for. The whole experience was very favorable . Everyone I has contact with was very professional and courteous. The salesman I worked with Joe Kendall was excellent. The day after the purchase I noticed that a light strip was missing on one of the outside mirrors. The service dept fixed it. In my opinion they are a top notch GM dealership . Keep up the good work😀
There are 20 matching cars close to your year range.
