Shout out to Sewell Chevrolet’s service department. They were so helpful and friendly. I ordered a front license plate holder. When it came in, the service technician offered to install it on my car. When I went to pay him for his service, he told me there was no charge. This is definitely where I will buy my next car!

I’ve purchased multiple vehicles from Sewell Chevrolet GMC and have consistently had a great experience every time. I’ve worked with several sales agents over the years and have also serviced all of my vehicles here. The staff is always friendly, attentive, and professional. At this point, I’m not a stranger walking into the dealership. They know us and treat us like valued customers. Highly recommend!
