I left a google review bc overall I've been pleased with your body shop and service department! Love the popcorn, cookies, and snacks. I felt very welcome, wonderful dealership. I've always been a Sewell customer bc of their customer service, but y'all exceeded my expectations and now I want to be a life long Ewing customer. We had a few communication issues between the body shop and service dept the other day, but other than that, very happy! Thank you so much, to Tag and Dan!

The customer service, the compassion and understanding
The customer service, the compassion and understanding were truly great. Suzanne and Jason were incredibly kind, very responsive and explanatory and provided us with all around amazing service. We were contacted quickly after our online inquiry and Suzanne was happy to help us answer all the questions we had. We are out of state and the process in which the paperwork and transport of the vehicles were done was flawless. We thank you all for your expertise and kindness. We will be back when the time comes and will most certainly refer all who are in the market to your dealership.
