Great Expereience
This was the easiest car buying experience I have had. They took me to the car I was interested in. Keys were there, we drove it right away. The price was competitive, the financing was lightning quick. They washed it while I was signing and I was out of there in under an hour. They even drove me to turn in my rental car so I could just drive my new car home and surprise the family. First class business.

I received EXCELLENT SERVICE when I walked into ALM Kia
I received EXCELLENT SERVICE when I walked into ALM Kia South on January 2nd. Kerry (Stan) Ellerbe, my Sales Agent is an Amazing guy. He walked me through the process with skill, knowledge, and patience. He made my experience an easy one. I drove off the lot with a brand new 2025 Kia Soul. I will definitely be purchasing my next "New" car from ALM Kia South. Thank You and God Bless all of you.
