buying at car max
As a retired tx DPS mvi trooper through my 30 years dealing with dealers carmax is most caring dealer. When we went to car max on gulf freeway to look for a new vehicle the salesman were very caring and helpful to find the velociraptor we wanted. We bought a 2916 Honda CRV with 10 mikes on the vehicle. We bought it. Service group was also caring and helpful. Keep up the good work. Larry parks.

Terard made my experience very easy.
Terard made my experience very easy. I am so glad he was our salesman. From the moment I walked in, Terard was welcoming, patient, and focused on helping me find the right vehicle. He listened to what I needed, and answered every question I had. Terard was professional and honest. He explained all the features, pricing, and options in a way that was easy to understand. No pressure. He went above and beyond to make sure I was comfortable with my choice. If you're looking for someone trustworthy and knowledgeable, I highly recommend Tarard, he is a good person! I wish him the best in life.
