“This is the second time I have taken my car to CMSC for an MOT and the service has been above what was expected. Dropped my car in for 8am an had a text an hour later saying it was ready to collect. Normally for the garages I have used previously I am waiting around all day or usually making the call. The staff were friendly and professional. I have already recommended”
