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😀

Buying my First car
I initially bought my car in July 2022. Our old family car broke down and needed a car. I had been window shopping for cars and looked but I didn?t see a car that stuck out to me until I saw the Buick Envision and fell in love with it and the color. The staff was super helpful throughout the buying process and I?m super happy with my purchase, I haven?t had my first oil change yet but I will def get that done soon at my dealer.

Replacement Rear Window Wiper Blade Cover
Somehow the rear window wiper blade cover on my 2019 Buick Encore went missing.... Being a long-time friend and customer of Mike's, I went to his GMC service center for replacement, and was grateful that Bill Haggerty replaced the missing cover without charge! As always been my experience, GREAT service and GREAT dealership! ...Tom Noble
