I took my 2008 Enclave in for a total replacement of my in dash Nav unit. I was extremely satisfied with the level of experience, fast work, very high quality workmanship ( not a carpet fiber out of place) and the very friendly customer services. Lastly, the price I was quoted was the price I paid - no attempt to upchage me for other stuff I did not need or to piecemeal me will additional cost. Very Very Satisfied! Dr. C. Brandon

The staff at Mas did a great job on our truck alarm. We have had it over a year. Just last week the truck wouldn't run. The owner of Mas sent one of his tect's over to my house, since I said it was the alarm. They checked it out and it wasn't the alarm it was the starter relay on the truck. They were quick to help us out. I would just like to say thanks for all your help
