I had an amazing car buying experience with Sam at John
I had an amazing car buying experience with Sam at John Miles Chevrolet! From start to finish, he was absolutely phenomenal. It had been over a decade since I last purchased a vehicle, so I was feeling a bit overwhelmed, but Sam made the entire process smooth, clear, and completely stress-free. He kept me in the loop every step of the way, especially about when the car would arrive in-state, and made sure I understood each part of the buying process. No pressure, no confusion?just honest, helpful guidance and great customer service. If you're looking for someone who?s knowledgeable, patient, and truly cares about helping you find the right vehicle, Sam is your guy. I couldn?t be happier with my experience!
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.

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.

In-and-out, fast service & NO stress... THANK YOU!
I went to Carmax on 4th of July. The place was not super packed, so that was great. We had a little 9th month old on tow, and were nervous that it would take us all day to shop. The only thing that took a lot of time was waiting for a sales man. Apparently, the new young guys at the front were more interested in flirting (yes flirting) with each other and playing around than realizing that we needed help or just plainly asking us if we were being helped. That really bothered me, as we wasted 30 mins just sitting dumb. The front desk girl was no help.. she was the one to tell us to sit and wait and then no where to be seen. Finally someone professional and extremely courteous walked by ... the service manager. He quickly apologized for our wait, and brought along Daniel Claudio. I am SOOOOOOOOOOOooooO thankful he did. Danny was professional, kind, humble, hard-working, and just all the way a pleasure to work with. He represented Carmax the way it should be. He took the details of what we were looking for and walked us around to cars that would fit our needs. The second car (nissan pathfinder) was a recommendation from him... and that was the car we bought. Danny if you're reading this... THANK YOU! You're such a great employee and that deserves recognition.
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!

Amazing!!!!!!
I had amazing Fast Pace experience even though it took me 3 days to get my car due to My inability to provide the documents they needed.however going on the lot getting pre-approved over the phone walking in and walking out with my vehicle was the easiest process I've ever faced. John was very helpful and Adrian was the greatest he worked with me every step of the way and he made sure I drove off the lot with the car i wanted. Even more so when I didn't even think or believe they can get me financed and not to mention they put a bow on the car I felt very special and the customer service made me feel very confident I am so grateful for you guys thank you so much CarMax!!!!!!!!!

Best car buying experience ever!
My sister, Deborah, and I went to CountrySide car lot in Jackson Georgia. We did not know what to expect, but we were hopeful. Our first impression was the warm and pleasant greeting we received from Trudi, the receptionist. Seconds later, Sales Professional, Nakia Bingham introduced himself. He was professional and very informative about the vehicle; he answered every question with clarity, and he addressed all concerns about the vehicle. Nakia was extremely patient with us; he made the process to purchase the vehicle go smoothly. I mostly appreciated Nakia for being honest and customer friendly. Thank you, Mr. Nakia Bingham, for your excellent service. You went above and beyond our expectations! This was the best car buying experience my sister ever had. I wish that anyone who want a professional car buying experience with excellent customer service, please remember… Nakia Bingham at CountrySide, Jackson, GA… He will do you right!

The oil change was done quite well. They did not honor the $9.99 price that was quoted to me in the text message that they sent. Why send a text when you are not going to honor it? That was quite disappointing. Other than that, the oil change and tire rotation was done in s timely manner.

I reached out to Platinum Cars Marietta about a BMW M850i
I reached out to Platinum Cars Marietta about a BMW M850i they had in their inventory, and I was thoroughly impressed with their professionalism and responsiveness. Jason Bush and David Patel promptly answered all my questions, providing clear and transparent details about the car and its pricing. Unfortunately, we couldn’t finalize the deal as the vehicle had a damaged part that they weren’t able to replace, but they did offer me a small discount to accommodate the issue, which I genuinely appreciated. However, since I’m investing over $50K in a car, I preferred to have it delivered fully fixed, so I decided to put the purchase on hold to explore other options. Despite this, I truly valued their transparency, urgency in addressing my concerns, and overall customer service. If you’re looking for a dealership that communicates well and is upfront about their inventory, I’d highly recommend Platinum Cars Marietta.

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 Customer Service and Assistance
The salesman (Jerrel) was great to work with because he helped me while he was there Orr if he was off that day. He got me a car from another store then found out there were problems and found me a car around the same price range that was newer and less miles. Thanks for everything!
