We had the best experience at the Arnie Bauer dealership!
We had the best experience at the Arnie Bauer dealership! As a first time car buyer, the process can be a little scary and overwhelming. However, Brandon and Alex were amazing. They walked me through every step and were beyond easy to work with. I could not imagine having gone somewhere else. Will definitely only be using them for car purchases in the future!

The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!
