Jackie was great!
Jackie was great! She was helpful and knowledgable. She seemed interested in helping me find exactly what I was looking for. I would highly recommend her.
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.

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😀
