Just had my 60,000 mi. Service and all went well! They also repaired a rain leak I found after the last storm. I?ve bought several autos from Jim Ellis and always have been pleased with sales and service . Ted and Harley in the Buick service dept .are the best!! I would recommend this dealer.

Great dealer for your custom order!
Worked with Ced Thatch in Sales on a truck order. Although I was unable to purchase due to my financial situation he was great to deal with through the whole process. The ordering process was quick and easy. Pricing was very good and my sales rep was very responsive throughout the wait anytime I had any questions. I would definitely recommend if you are looking to order a truck or SUV even from out of state. This is a big dealer with lots to choose from and a solid office team to help with your purchase.

I absolutely loved the service that my family and I
I absolutely loved the service that my family and I received from Riley. He was very thorough and knowledgeable about all that he spoke to us on and we felt very comfortable with working with him. I HIGHLY recommend anyone who is or will be looking for a new car to visit Southtowne Newnan and work with Riley.

Best experience so far, and I have had many
I have purchased new and used cars before, from different dealerships all over the Atlanta area. A total of 10 counting this one. Plus 2 bikes, but I'm not counting those. I have had absolutely TERRIBLE experiences, and I have had okay experiences. This was, without a doubt the best of them. What made the difference- Sam Rangel. My wife shopped around online and found a van she wanted to look at, and it happened to be at the Hardy Superstore. She went by herself to check it out. She met Sam. Sam was the opposite of what many come to think of when they think of a used car salesman. Sam was very kind and helped her. He listened to her and genuinely desired to help her find what she was looking for. I know most good sales people are like that, but there are some that don't have a customer service quality to them, but Sam does. She never felt pressured. Sam made us feel like he was on our side of things- whether it was the vehicle, the negotiation, the financing, or whatever. He was our representative. I love looking at cars, and investigating them, but absolutely HATE haggling and the actual car buying part. Sitting and waiting forever, going back and forth. Then when you are done, you have to wait for the vehicle to be cleaned and gassed...ugh. Did I say I HATE car buying? So this time, I done the whole deal with Sam through text messaging! A first for me. Whenever I asked for something, Sam replied. Sam's manager, and Finance closer- Mitch Feraco made a great team. And he had the van ready so when we got there, we signed and drove away! So, if you find a vehicle at the Hardy Superstore, or need someone to help you find one, call Sam Rangel- you wont regret it. Tell Sam I sent you, he will take great care of you!

The customer service was great.
The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.

Love my 2020 Mazda CX5 Grand Touring
Great experience with Hennessy of Southlake. Frank Parker was awesome and represented the dealership well. I flew in from Memphis, was picked up from the airport and everything about the car was as represented online.
