There was plenty of inventory on the lot, in the price range I had in mind, and the buying experience was stress-free and pleasant! Perry York is a seasoned salesman and it was a pleasure negotiating with him. He made it so easy.

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.

I texted Mr. McGowan about getting an appointment, which he set up promptly. He managed my service visit, including providing transportation while my car was being serviced. Great customer service and professionalism!
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.

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.

I went into the dealership knowing what vehicle I wanted. I was assisted by Alex who was extremely helpful and knowledgable. Alex is personable without being pushy and gives off the aura that he genuinely cars abt his customers. The entire staff at Calavan was outstanding. This is my 2nd Sorento purchased from them and would recommend this dealership to anyone in the market for a car.

Great service from Garry
I didn't end up buying the used car I was looking for, but wanted to leave a positive review for Garry, the salesperson who helped me, and the dealership as a whole. This is a nicely-appointed place, as you might expect from the high-end cars that they sell. Everyone was friendly and helpful and there was no high-pressure sales pitch. Ultimately I chose a different car at a different dealer, but I can't complain at all about these folks.

Great service. Except for
Peter was the first person who helped me and was very helpful, when I had a family emergency he held my Mustang till I could get in to see it. Kern was the individual who I saw when I was able to see the car. He was very helpful and got me quickly through the process. The only problem I had was the rocker stripe was missing on the passenger side is missing and they have not been able to get it replaced. Hopefully it will be resolved soon.

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!

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.

I was in the market for a new car for over a year now.
I was in the market for a new car for over a year now. It is nerve wrecking and overwhelming. Decide to buy a new or used. I researched, test drive, and contacted over 20 dealers for information. Until I finally found the perfect car for me at the perfect price, while on the CarMax website in Norcross, GA. A 2023 Nissan Pathfinder SV 4WD with 16,500 miles. Practically brand new and at least under $2,000 and the lowest miles from similar vehicles in my area. One great thing about CarMax is that I was able to scheduled the test drive 7 days in advance. They reserved the car for me, no worries about being sold before my test drive. Another great thing about CarMax is the price advertised is the price you pay. Other than tax, title and registration, no other “bogus” fees are added to the price. I only wish they offered special incentives/discounts like military, first responders, student, etc. But, I am extremely happy with my purchase!!! Shout out to salesman Young!!! He is the first person I spoke to; he got the car for my test drive, and in less than 1-2hrs I was on my way home with a new car!!! In other words, DO YOUR RESEARCH!!!
