  • Auffenberg has completely simplified the car buying process for me and my family. Great Staff reliable service and we hold them at high standards. Incomparable to any other dealership in the metro east area.
  • I would recommend Auffenberg Kia to all of my family and friends!!!! The staff is very helpful and go out of their way to help their customer!!!!!!
  • I just bought a Mazda CX-5 the other night from Jason Hall. The service my husband and I received far exceeded the service I have received else where. The car was flawless and everything was done quickly and professionally. Will be going back in the future.
  • Best car buying experience ever! Jimmie Rines and Derrick Thomas have taken fantastic care of us, as well as the rest of the staff!
  • TJ Chilton is awesome! He made the process very stress free & easy to understand. I highly recommend him to anyone wanting to purchase a car.
  • At first it was a little rocky (as much as it is with any car buying experience) but in the end Ian Forshee (salesman) and Mike Brewer (sales manager) came through for me and got me a deal I was happy with and will continue to bring my business to them in the future.
  • This was a wonderful car buying experience. The salesman Matt was very clear and precise and was able to get me into the car I want and not what they wanted to sell. I'd definitely recommend this dealership and especially Matt. If I ever need another car this is where I plan to go!
  • We got a great preowned transit from Matt and we are very happy with our purchase. Thanks Auffenberg!
  • I had a great experience buying my new car from Auffenberg Kia. Jeremy Higgins was a joy to work with. It was by far the best car buying experience I've ever had!
  • My son and I walked into Auffenburg not knowing what to expect. I met Anthony Leck who was just fabulous. He put my nerves to rest. I felt confident that he was a genuinely nice guy. I walked out with the car that I wanted.The experience was super. Thanx to Anthony Leck.
  • Our Kia broke down on Fri afternoon. Kia had it towed immediately and a rental car waiting. Kia was fixed by noon on Monday. AWESOME SERVICE***
  • Brandon blue. Great service. Got right to the point no bull. Highly recommended for your next vehicle purchase.
