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.

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.

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.
Great vehicle
This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

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.

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!
