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.

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!!!!!!!!!
GLC43AMG

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.

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.

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 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 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!!!

The Hyundai Tucson car I came to see and hoped to purchase was sold a couple hours prior to my arriving. I was a little disappointed, but Tim came to the rescue and with my children on the phone, I left with an Audi Q5. The team of Tim, Marcus, and Mark in Finance helped and got me in the Q5! I am excited with the outcome!
