I worked with Johnie S.
I worked with Johnie S. and I would highly recommended him to anyone looking for a new car. Even when we were in the heat of negotiations he was polite, respectful, and transparent. Are negotiating via text on a specific vehicle he was able to send us all the documents over email and got us in and out of the dealership in 90m. Wayne in finance was extremely friendly, pleasant, and made a typically painful process painless. It?s clear the manager Steve has this place running smoothly.

My truck maintenance was handled promptly with
My truck maintenance was handled promptly with professionalism. When I went to pay for the service however, they wanted an additional 28$ on a 1K bill to use a credit card. A debit wouldn't incur this fee. This seems like usury and seems over the top.
2021 GMC Sierra Denali

I came to your dealership to find a "good" used car, but
I came to your dealership to find a "good" used car, but had no real idea what i was looking for. I was given immediate attention. I told the guy who came up to me that I wanted a "small" car, and he told me he had only one @ this dealership, and he proceeded to show me the Fiat 500, which I took on a test drive and subsequently purchased. When I went inside the "offices area inside", Alexis Drake came up to me right away, and she proceeded to do all of the paperwork, then I saw another fellow doing more paperwork, etc. They proceeded to get gas before purchase, and my car was returned to me having been through a long checklist of tests, and it was clean, polished and looking good.

Juwal, Travis and financing or seamless and didn’t harass us to add add-ons because I told what my budget was upfront and when I needed the car to do and they found that car and they made it fit my budget and I’m talking about cash budget out the door cause I don’t do car payments They are lovely lovely people they’ve called to check on the car and me and my daughter because we need the car for the safety features because of our medical issues this dealership treats you as though you are family which is greatly appreciated in a really cruel world.
