This is the best car place EVER! I can usually drive right in and get my car services. They always give me honest and fair advice; their prices are great; and they even helped me when I had to see my car. I will NEVER use anyone else but them. Jeff and Michael are the best. As a single woman, I feel like I can put my trust in them.

During a trying time when my engine went out completely, the staff at CBA was amazing, specifically Jenny. I felt like a truly valued customer who was greatly appreciated for doing business with them. Jenny went above and beyond to make this difficult and costly repair as painless as possible.

Master Auto Tech is the best I took my BMW 750 in for low water level other shops said it would be 1000-1500 after they look at it, Antonio said to bring it and said 200.00 for the repairs. They were fast to complete.

I was ready to leave Loyd Park in Grand Prairie and the front air leveling system was leaking air and would not raise the motorhome. Not drivable. So, I called Quality RV repair who I've done business with before, but turn out they don't work on the Freightliner chassis. Seconds later she is giving me Tommy's name and number. I called it but got voicemail. It was getting late in the day. My family had already gone home, so I called and arranged for another night, thinking Tommy probably would not call back. But a short time later Tommy did call. Said he would be out soon. Soon was very soon as it turned out. You don't find service people like Tommy very often. He crawled under the bus and determined the valve needed to be replaced. He called several places and left with the bad valve as one place said the may have one. Turns out no, but Freightliner Dallas did and he put it in will call. I drove to Dallas and picked up the part that night. Tommy met me back at the campsite 7 ish the next morning and fixed it. Apparently this part had been partially bad for a long time. My Motorhome rides better, handles better, is much quitter and sets higher then before. When I park I can tell the volume of air being released is much greater than bofore. Can't say enough good about Tommy. He gave me a very reasonable rate for his labor as well. We need more Tommy's in the world. Ken

These guys are the most honest mechanics I have ever encountered. When others wanted to charge me for frivolous work that did not need to be done, Conerstone was there for me and fixed everything right the first time. Their rates are very reasonable, and it is the only place I have used for the last 5 years. Great reputation!
