We worked with Brian Newcomb to purchase a new 2025 Buick
We worked with Brian Newcomb to purchase a new 2025 Buick enclave. From the moment we walked in the door, we felt at ease and were comfortable. Brian was down to earth, honest, and personable. He was knowledgeable and was able to answer all questions. We highly recommend Brian. He made the whole process headache free and easy!
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😀

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.

Thanks Marcin Kenny & Jimmy
An unforgettable experience to say the least. This is my 3rd new vehicle and by far the easiest and most hassle free. My salesman Marcin and manager Kenny went above and beyond for me to locate the perfect vehicle to fit my wants and needs along with staying in my budget. Jimmy also got me in and out with paperwork. Would definitely recommend all family and friends! Thanks Rizza GMC!

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

I had major work done on my car and I couldn?
I had major work done on my car and I couldn?t be happier with the turnout. I had my transmission replaced along with a couple other issues on my 2017 vehicle. It took a while for the entire thing to get completed, but I was given status updates throughout the process. I picked up my vehicle late last night (5:45 pm). I was surprised the service manager was still there and he took the time to go over everything that had been done to my vehicle. The total price was slightly lower than what I was I was told it would be at the start. I was very happy and wasn?t expecting that. My car is driving great today and so far I?m extremely happy with the result from my service experience. I?m very appreciative of the help I was given and the customer service I received. Thank you Justin and everyone who worked on my car. ?
