Very happy with my time there. Very friendly staff.

The two sales people I worked with were both very kind to work with. I was disappointed in other aspects that were out of their control. Keeping their names and perhaps will try again in the future.

I want to thank Dallas Buck, Aaron Havill, and Stephanie for helping me solve a problem.

Had a great time at the dealership working with Austin. Super chill, easy to talk to, and actually made the whole process enjoyable (which is rare when buying a car). No pressure, just good vibes and solid help from start to finish. If you’re heading in, definitely hit up Austin—he’ll take care of you.

Picked up our 25 Acadia last week! Had a great experience with Bob Brown GMC. Joe was excellent to work with. He was pleasant, and knowledgeable on the cars, both on the lot and after the sale showing us how the vehicle works (it has some things new to us). Communications on phone, email or text was prompt and courteous. Brenna was great on finance also! Joe even took time to show us the service area. Thanks everyone! 👍🏼

I'd give these guys 10 stars if I could...I spent 25 years in the car business and most of it in upper management. I was coming from several hours away and my Sales Mgr Aaron Havill made me comfortable enough to make the trip with confidence. Aaron greeted me promptly and the vehicle was standing tall inside the showroom delivery lane, looking better in person than the multiple pics and videos Aaron had personally sent me. My salesperson Aaron Mohler made the test drive, setup and final legwork of the deal equally as pleasant. Adell Hilson completed my paperwork and extended warranty transaction timely and professionally. From 25 years experience in the business, and talking with several dealerships in my buying process, these guys were head and shoulders above the rest! Thank you

I had done a little online looking before my visit. Texts were answered promptly by Austin, I went down the next day and purchased my Blazer with him. Very kind and courteous!! Smooth and easy process.

Austin was excellent to work with. He was genuine and not pushy. The process was very smooth. Would absolutely purchase from them again.

If you’re looking for a new or used vehicle and want to have a great experience reach out to Kyreef Prezzy at Bob Brown GMC! Kyreef was pleasant, knowledgable and took the extra steps to ensure that my decision to buy my used 2024 GMC Denali was the right one. Thanks Kyreef for your unique way of making all around you feel welcome and not pressured.
