My shopping experience @CarMax Roswell, Ga
My overall experience with this dealership and sales associates were very pleasant and sufficient. I was able to take my time in selecting my vehicle and was given accurate pricing info as I had already did my research for the car I was interested in. I wasn't pushed into a car I didn't want or desire after I decline to purchase the original car I went to the dealership to test drive. The associate took the time to look through the online lists of cars within a 150 miles of his dealership and after locating a car that I liked he was able to have the car transferred in from another state free of charge. I was called when the car arrived and made an appointment to check it out and I made a purchase.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Selling my car through AutoNation was an outstanding
Selling my car through AutoNation was an outstanding experience, thanks to the exceptional service provided by Amogh and the support of Sales Manager Fanny. From the moment I walked in, I was met with professionalism, transparency, and a genuine commitment to making the process as smooth as possible. Amogh greeted me with a warm and friendly demeanor, immediately putting me at ease. He took the time to explain every step of the car-selling process in detail, ensuring I understood how my vehicle would be appraised and what to expect. His thoroughness and patience made a significant difference, as he answered all my questions and never made me feel rushed or pressured. During the appraisal, Amogh carefully inspected my vehicle and provided a clear breakdown of its value. He pointed out both the strengths and any factors that might impact the final offer, giving me a complete picture of the evaluation process. His honesty and expertise were truly appreciated, and it was evident that he wanted to get me the best possible deal. Once the appraisal was complete, Sales Manager Fanny stepped in to review the offer with me. She was incredibly professional and knowledgeable, taking the time to ensure I was comfortable with the numbers presented. Fanny was transparent about how they arrived at the valuation and reassured me that there were no hidden fees or surprises. Her confidence and experience made me feel secure in my decision to proceed with the sale. When it came time to finalize the paperwork, both Amogh and Fanny worked efficiently to make the process quick and hassle-free. Amogh guided me through every document, explaining each step with clarity. The entire transaction was smooth, and I never once felt overwhelmed or uncertain. Even after the sale was completed, Amogh and Fanny followed up to ensure I was satisfied with my experience. Their dedication to customer service went above and beyond, proving that AutoNation truly values its clients. Selling a car can often be stressful, but with professionals like Amogh and Fanny at AutoNation, the process becomes seamless and even enjoyable. Their integrity, expertise, and customer-focused approach set them apart, and I would highly recommend them to anyone looking to sell their vehicle with confidence and ease.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

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.

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.

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!!!!!!!!!
