I recently bought a car for my 16 year old daughter from South County Auto Plaza and could not have asked for a better experience. The process was stress free and I got a quality car at a fair price. Go see Dylan Kilbourne and he will treat you right and he is super responsive as well! The customer service side was just as great- shout out to Jason on their team. I would buy another car from them without thinking twice about it.

Jeff was amazing! No pressure and went over what they needed to do to the vehicle. After sale was also a great experience. They did 100% what they promised! I highly recommend South County Auto Plaza and ask for Jeff, he will take care of you!!

Burton was fantastic, he helped explain details and looked into anything i had a question on while I was in looking at cars and helped me feel confident with my purchase. Everyone was helpful and they take the time to really explain and give details about warranties, coverage and more. I will definitely recommend to others based off my experience.

Posting on behalf of my son I co-signed for tonight with Brandon at SCAP. His first “adult” purchase at 19 and he couldn’t be more excited. Thanks to the whole team at SCAP especially Brandon. Popcorn was good bro. Haha Would definitely recommend and would be a repeat customer

Brandon took care of us today we didn’t even plan on getting a truck today and he made sure we were taken care of and was super friendly and personable. He’s very professional and is upfront and honest about everything!!
