Jeff was excellent, fun and easy to work with. He made us feel comfortable buying our Nissan Rogue and explained everything to us thoroughly. We appreciated his patience and honesty when answering our questions.

No one wants to go through this headache ever. Thanks to Mr. Burton and his very respectful and helpful team we were in and out, everyone satisfied. Would recommend 110% will be coming back to him and them for our daughters vehicle later this summer!

I was looking for my first car and I came to SouthCounty AutoPlaza. Dylan Kilbourne was amazing! He sold me my first car and it was a wonderful experience. I wouldn’t have wanted to go anywhere else.
