Amazing place to buy a car
Amazing experience. I'd recommend anyone looking for a car to try CarMax first... There's zero pressure, tons of beautiful vehicles, and just an all around great place. Will definitely be buying from here in the future. They're willing to work with you if you don't have the best credit, and most importantly, they're just honest and transparent. Two very important things when spending tens of thousands of dollars. Put it this way, it was great enough experience for me to come online and leave reviews all over!
Shout out to Genesis for helping us get our dream car ,

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.

Chris Etheridge was exceptional, professional, listened, and made our sale smooth in little time. Those days of sitting in a dealership are over. Thank you Chris we look forward to working with you in the future and will give out referrals for sure.
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 have worked with Brian for quite a while and I have been exceptionally pleased with the service that he has given me. I feel very comfortable having Brian in charge with the service department because he stays on top of what has to be done. I have found that Brian is very caring, professional, and knowledgeable and when I leave the dealership I know that everything was done perfectly. Janet Edsall Fields

I am extremely pleased with the customer service dept.
I am extremely pleased with the customer service dept. Nathan was courteous and listened to all my questions and had the answers for me. I came in on a Saturday for express service for a dead battery and received my car back fixed in a timely fashion. I will more than likely buy my next car from flagship motors, and I will recommend them to my family and friends. Thank you very much and keep up the extraordinary service. Harry Dragonis
