 "This relationship is so strong that when we moved out of the Belleville area and thought we would have to find another automotive shop, they stepped up to help. I work in Swansea so even though we don't live in the area anymore I still come for work. Therefore Stock's comes to my place of work and picks up my vehicle for service and brings it back by the end of my work day. We did not ask for this; they offered it to us to keep us as customers. I think that says it all."
