Everyone was very polite and professional.
Everyone was very polite and professional. The finance department was fast. Very courteous and was the expectation and they delivered. I only wish the overall process was a bit quicker.

Went to see Dominique at Ron Craft off I10 in Baytown he
Went to see Dominique at Ron Craft off I10 in Baytown he was very nice very helpful...he was laid back and not pushy at all like some sales people can be..we went back and forth several times with his manager on negotiating a good fair price until we got the numbers where we wanted it we had a deal, he was patient so thats a plus! Ive even texted him asking for help in my computer screen in my car and he didn't have an issue at all in helping over the phone. Im glad our daughter and son n law referred us to him, it seem easy n effortless even though we were there for maybe 3-3 1/2 hrs it really didnt seem that long...thanks Dom!

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.
