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.

I recently talked to Jeff about buying a car a couple months ago. He tried working with me but I was young and had no money down. Any dealer would’ve ran your credit like no other but he stopped me and told me to come back later. Here I am today buying a car from Jeff an he has worked with me like no other. It was like he treated me as his own son with financial advice and worked with me so much that it made spending this money a delight.

I went to South County Auto Plaza today and found a beautiful car w help from a very cool sales representative named Dylan Kilbourne, who went out of his way to get me in the car I wanted. South County Auto Plaza had a good selection of cars w lower miles and lower prices than any other used dealership I found. I am very happy w my purchase . Thank you.

Out of all of the cars I’ve looked at, Jeff took care of me! He was thorough, educational, and made me feel like I can trust him and this business. I’m happy with my purchase and excited to have a new car!
