The work is done in a very timely manner. They provide an estimate before performing the service and, in my experience, it is within 5% (usually less) of the actual total.
The shop is very clean and organized; always a good omen. The real kicker are the waiting areas. They are very clean and comfortable. A desk was provided for me in a quiet corner of the building. The final attribute that is a real tell about the class of this operation is the seemingly minuscule fact that their spotless rest rooms have hot water for washing one's hands.
