I drove from Omaha because they had a truck I was interested in. Rick did an amazing job as my contact person. He was very personable and easy to talk with. I ran into an issue when I got back to Omaha and he was willing to work with his manager to help me out. Luckily it resolved itself but glad they were willing to help.

First time interacting with Bob Brown Buick GMC on a new vehicle. Kamrie was a delight to work with! Super responsive to my initial phone inquiry and set up a good time to stop in, same day! Great personality and very welcoming to assist! Was able to find a vehicle that was really appealing and met the marks! Nice, clean dealership with a variety of automotive options. Also, great encounter with Gene in Finance, easy, seamless process and was promptly ready to sign, seal and deliver! Thank you for a wonderful experience!

What an excellent experience at Bob Brown Buick GMC. Shane Luing was as good as it gets with being knowledgeable, respectful, kind, caring and understanding and working with our needs.

UPDATE: The team reached out and has been helpful in getting the issues resolved. Previous: Recently purchased a used truck from Bob Brown Ankeny. After multiple delays in receiving the truck I discovered the driver side mirror had issues and one speaker was blown out. After reaching out I was told "You bought it "as is" and should have purchased one of our warranties." I understand it was a used truck but expected to be purchasing a quality vehicle or would have been told about such issues as I was not offered a test drive.

Very polite and knowledgeable about each vehicle we asked about. Took time to explain the features that we would benefit from with our large family. Will be coming back for any future car needs!

No one loves getting their car serviced, but the Service Dept here at Bob Brown makes it a little less painful. Everyone is friendly and respectful. Your service advisor will keep you informed every step of the way. When service is completed, the cashier is efficient and thorough.

My husband and I had a great experience when buying our 2025 GMC Terrain. Our sales person Rick was very helpful and patient with us and all of our questions. Made process so easy and pleasant. This was our 2nd vehicle we have bought there and definitely will go back for our next purchase.
