2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

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.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

2015 Subaru Outback ( Grey)
Hands down this was the most pleasant and stress free car buying experience EVER! My senior sales consultant was Shenita Monroe at Carmax Norcross , who was an excellent salesperson to buy my 2015 Subaru Outback car from . Highly professional , courteous and detailed , are the words that come to mind to describe her exemplorary customer service style . We initially enquired about the vehicle online and discovered it was at the Kennesaw Carmax location . She immediately requested a transfer so that within 24 hours we could conveniently test drive and finally purchase the car. She is the real deal and we can't recommend her enough . Please make this woman a sales manager !! 5 STARS...

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.

After entering my 2020 E450, I got a display message that said "12V Battery. See Operator's Manual". Sent a quick note to Mitch Griffin thinking after 5 years a new battery was probably needed. He responded and after contacting RBM, Jordin Mendez was dispatched to my house. In about 20 minutes, the battery was replaced. Great job by Mitch, Jordin and my phone contact at RBM. Much appreciated!
