Buying our vehicle at Kelley Buick GMC was a great
Buying our vehicle at Kelley Buick GMC was a great experience. Our Sales Consultant Braxton Nyland was waiting for us with the vehicle ready to test drive. We loved the vehicle and proceeded to the showroom to work out the details. To our surprise everything was up front and open, no exhausting back and forth. The General Sales Manager Brandon Wundrow also checked to make sure we had everything we needed and thanked us for our business! In no time our new vehicle was ready to drive off the lot!
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Drew Koba is the best Parts person you have
Drew Koba in the Parts Department is such an asset to the company. I have used him for years and would recommend him and this dealership to anyone. He is personable and extremely professional. It is almost as though you think you are talking to your long-lost friend. As a business, he is the type of employee you want. He keeps me, and I am sure others, coming back again and again.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Had an initial bad experience with this service center
Had an initial bad experience with this service center but once the service manager (George) contacted me and ask for a chance to earn my business back I agreed to give it another shot. George was very attentive e to what I needed and gave me updates as the work was completed. I must say I am very impressed with the work and will from now on use this service center for any future service issues. Very satisfied.

The dealership was the best we have ever dealt with, and
The dealership was the best we have ever dealt with, and it started with meeting Clay Vogel on the lot. Found the truck we were interested in, he communicated a deal with his Manager, and continued the process in a very professional and patient manner until complete. I would absolutely return in the future. Thanks all involved.

I had an excellent experience at Kelley Buick GMC.
I had an excellent experience at Kelley Buick GMC. From start to finish, the team treated me with professionalism, honesty, and respect. They took the time to answer all my questions, walked me through every detail without pressure, and made sure I got exactly what I was looking for. A special thanks to Gustavo Sanchez and Russell Hernandez — both went above and beyond to make sure the entire process was smooth and stress-free. They were knowledgeable, patient, and genuinely cared about finding the best fit for me. The finance process was straightforward, the dealership was clean and welcoming, and I never once felt rushed or “sold.” If you’re looking for a dealership that values customer service and treats you right, Kelley Buick GMC is the place to go. I’ll definitely be back for my next vehicle.
