LovesNavigators
everything was great, nice people, quick service, loaner car. We've purchased 6 cars from Pugmire since 1990 and used their service on every car. Barry and the other guys in Service are great, couldn't be nicer, they don't do work that isn't necessary. And it was a pleasure to buy our last car from Nathan. Just saw the 2018 Navigator. Wow! Might be visiting Nathan again soon. Best Dealership in Atlanta. They aren't near my house but worth the drive.

Our daughter had been wanting a specific Tundra with specific items for a very long time. She saw one online so her dad and I went to look. We knew immediately it had her name all over it. Tim was wonderful in helping us from beginning to end. It was an extremely pleasant experience. Their facility it beautiful, has everything you might need and so clean. The staff are all smiles, friendly and willing to be helpful. For anyone looking at Toyotas, this is the place to go.

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.

Scott S.
Scott S. was a great help to me with the sales team. Met Scott for a test drive, and he was very knowledgeable and helpful without being pushy. The service department had to work on the truck I was interested in before it was ready to be sold, and he kept me updated and informed throughout the process. Although I ultimately bought a different vehicle, it certainly had nothing to do with Scott. Would happily reach out to him in the future or recommend him to anyone else in the market.

I just want to say that I had a very professional
I just want to say that I had a very professional customer service experience with Ryan Ramdass and wanted to write a review to express my gratitude. Ryan and I had an issue that we had to address and resolve over the phone and he handled it very professional and cautiously. I would recommend Ryan to anyone who is searching for their next Chevrolet! He is a top notch salesman in my book. I his straight forward and to the point and says it like it is and I appreciate that about him and our conversation. Ask for Ryan when you look to purchase your next car he will not let you down.
