“I recently purchased a Cadillac from CarMax of Gaithersburg, and I have to highlight the outstanding service I received from Edward Alcalde. In an era where customer service can sometimes feel forgotten, Edward truly stands out. He was honest, forthcoming, and showed immense integrity in his work. You can tell he genuinely enjoys what he does! He was extremely hospitable, answered all my questions, and got back to me promptly, helping me when others couldn't. I am truly appreciative of his efforts, and he is a wonderful asset to the CarMax team. I look forward to future business with him and CarMax of Gaithersburg!”

“My experience at CarMax was good overall. The process was simple and well organized. The team was helpful and explained the financing and paperwork clearly. While the wait time was a little longer than expected, everything else went smoothly. I’m happy with my purchase and would consider CarMax again.”

“5-star experience. Purchasing was a breeze, and currently the warranty service the car needs has been a very pleasant and professional experience. Love the 10-day return window & 90-day warranty. Absolute peace of mind. Gordon in sales and Michael in service are a joy to work with. Friendly, professional, very accommodating. Would purchase from CarMax again in a heartbeat.”

“We enjoyed a terrific experience here at CarMax in Gaithersburg/Shady Grove to sell my Mom's 2010 Toyota Tacoma pickup truck.
I wasn't sure what to expect at CarMax, given it had been at least 15 years since our previous engagement with them.
Happily, the facility is well designed, superbly organized and staffed by just about the happiest personnel I could imagine.
Outstanding people in particular were Queenia and Mindy, who worked patiently with me over 2 days back and forth as I gathered all the paperwork in order.
Whether you're selling or buying, be sure to visit CarMax Shady Grove!”

“I sold my car at CarMax recently. The best part was how fast the appraisal process was. They had me pull up, checked the car, and gave me an offer within about 30 minutes. The offer itself was fair, and in line with what I had seen online, which I appreciated. The actual payment process was also smooth. I had the check in hand the same day.
Where things fell short was the customer service and communication. Even with an appointment, I felt like I was just another number in line. The staff didn’t explain much unless I asked directly, like how they came up with the offer or what would happen with the title paperwork. It felt a little rushed and transactional, without much effort to make the experience more personal.
Another frustration was the wait once I accepted the offer, almost an hour of sitting around for them to “process paperwork.” For a place that markets convenience, that part dragged on longer than it should have.
If you want a quick and straightforward way to sell your car without dealing with private buyers, CarMax works. But don’t expect top dollar or a polished, customer-focused experience.”
