Best customer service
Bought a new Mustang awhile back. Great experience with Edwin Torres. Since then have used their service department for everything including all oil changes and I drive 35 miles each way to do so. Why. The treatment by everyone is 5 star every time. Recently had an issue that was resolved by staff that would have been a nightmare at a corporate owned dealership. Bill Currie cares about their customers, it's not just lip service. Highly recommend them. Sales and service.

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!

Purchased 2005 PT cruiser, not running right.
We purchased a 2005 PT cruiser which just wasn't running right. We took it to Thunder Chrysler for repairs. It took three visits to the service department, a lot of perseverance and a lot of detective work, but they got it fixed and running right. Very satisfied. Thank you.

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.

My sales associate, Trenton Jump, responded immediately and effectively. Every question I had, he either had the answer, or knew where to get it. I bought the car from Arizona, and being across the country didn't cause any problems. Trenton was a true pro and helped me tremendously.
