They diagnosed my truck accurately, and get it right the first time around. My truck is a 1999 with relatively low miles. Of course I can replace just about everything, but CCAS pinpoints the problem and fixes it the first time, and only as needed. I have not had that same experience with other mechanics.

by - Verified Customer February 28, 2014

The staff is very professional, they take the time to explain the work that will be done, and provide recommendations of work that may be needed in the future. Price for work is also fair.

by - Verified Customer February 24, 2014
