I would buy here again!
George was very helpful and knowledgeable. He made the entire process easy and enjoyable. The dealership even included a lifetime powertrain warranty, which is something I have never heard of any other dealer doing. I highly recommend George and Foundation Kia…they were a breath of fresh air!

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.
2021 GMC Sierra Denali

It was a fantastic place to buy a car. Drive time a little long but had what I wanted so bought it. It was described as great as it was. Felt like no question was a stupid one.
