We could not be happier with our experience and purchase!
We could not be happier with our experience and purchase! Our salesperson, Vince, was helpful, knowledgeable and went above and beyond to ensure we were happy with our purchase. We came all the way from Gwinnett, and are so glad we did! If you want a dealership that treats you with respect, is efficient and doesn't play games- this is where you need to look. I highly recommend you talk to Vince, especially if you are looking for a pre-owned Audi.

About everything that I experienced at this dealership
About everything that I experienced at this dealership was outstanding, my service advisor Patrick was on point he was very kind and courteous and had no issue speaking to me multiple times 2 weeks prior to me coming in for my appointment. I got to speak with both the service manager and service director while I was there and they were both too amazing individuals. I brought my 2014 Taurus SHO performance package in to get a PTU flush and a brake fluid exchange and I was only there for maybe 4 hours. As a fellow service advisor that works for a different dealership I can say that my expectations were met and I was provided the same customer service that I strive to give my own customers. I was a technician for 13 years prior to becoming advisor so I am capable of doing my own work however it's establishments like this that make me not feel so bad about paying someone else to repair my vehicle ?. Hats off to the dealership, I would highly recommend using them for your next service. I did speak to the sales department briefly and they were pretty awesome too they were not super pushy when I told them I was only looking and I was not necessarily in the market and they still took me on test drives and answered all the questions I had.

I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Very good experience. Very easy to deal with. Very professional in all aspects of the transaction. I would highly recommend ALM Kia South.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

My recent experience with Russ at the Tampa/St.
My recent experience with Russ at the Tampa/St. Petersburg location was phenomenal. They did everything that they said they would do in terms of service, price, etc.. I received great value for my automobile which they purchased and they even added a bonus on top of the price they quoted me. The transfer experience was quick, simple and seamless. I highly recommend having a conversation with these guys.
Great vehicle
This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it
