Great service
Needed a battery ASAP. Stopped in to see when I could get one installed at 5:00 pm. Heath said they could do it right now. No appointment needed. We were out before 6:00. A $20.00 rebate and great warranty made the deal even sweeter. If you have a Ford don't bother shopping around like I did. Just go here.
This truck has a jerk when changing gears sometimes.

Great Day @ CarMax!
A few weeks ago my son and I bought a 2016 Hyundai Sonata at CarMax of Southlake on Mt. Zion Road in Stockbridge GA. Our sales agent was an older gentleman named Jim Lowe. What a nice guy. Low key. Not pushy. So very patient. He was very knowledgeable about the various cars my son wanted to look at and understood what features he needed on the car. He never rushed us to get on to the next customer and was always willing to answer all our questions. (And he even knew the answers and didn’t have to go ask someone.) These are attributes that you don’t always find with used car salesmen. But Jim was different. CarMax is different. Such a large selection of cars that we found and with low or mid or high mileage. The financial process was painless as well. We went outside to go get his car and found it all washed and cleaned inside. It even had a full tank of gas and a HUGE yellow bow across the hood. Such a nice way to send off the customer. I highly recommend CarMax for your next car buying experience. Also, ask for Jim.

I would like to share my experience here and dealing with
I would like to share my experience here and dealing with Travis over the last week and a half. My wife and I contacted him about a 2017 Audi R8 on a Saturday that we were in Atlanta for a Braves game. I told him we were interested in looking at the car for potential purchase. It was last minute, but he told me "sure come on, the car is here, and you can check it out". We drove to see him and when we got there, he greeted us and introduced himself and showed the car to us. He offered to take me for a ride to check it out and was very pleasant to deal with. After we were done, he told me he would take care of getting the financing done and would try to get me the best deal possible. After staying in contact with him about the car for about a week, he delivered on his word of getting the financing done. My wife and I went back and forth on whether we wanted to spend the money or not. Even after being indecisive about the purchase, he stayed patient with us and wasn't pushy. So, we finally told him we would come get the car and sign the paperwork. Once we arrived, I asked him if we could check the car over really good one last time before signing. He was cool with it and because we were already approved and had insurance on it, he said, "here take it out for a spin and let your wife see what it's like and when you are done come back and let's talk." We really enjoyed the car and told him when we got back that we wanted to discuss everything over lunch and would give him the final answer after eating. Ater talking, there was just a few issues that were concerning to me about going forward with the purchase. To be honest, they may not have been big deals but for us purchasing a car like this for the first time we figured it would be best to wait until we find one that just made everything feel right. He understood and even offered to take care of the issues, but my wife and I just still weren't there on the car. As an owner of a European car repair shop there was just a few things that made me not want to go through with it. The R8 was beautiful and felt solid and like I said it was small things that probably wasn't a big deal, but they changed my mind. We didn't go through with the purchase, but it had nothing to do with Travis and how he conducted business. It was just mainly me being nitpicky on things. I never asked him to take care of the issues at all. He offered to do it. So, I must say coming from a business owner myself and dealing with customers on cars, I appreciate that a lot. He was very professional and easy to talk to. I would still consider purchasing an R8 from him if he were to get anymore that just makes my wife and I say, "yes this is the one for sure". I understand that everyone is going to have a different opinion about a business and their experience, and you can't please everyone all the time. I deal with it at my shop from time to time. I'm basing my review off of my personal experience here. Travis, if you read this man, we genuinely appreciate your time, professionalism and integrity. Thank you for being patient with us and I'm sorry we couldn't make a deal at the time.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!
