How long has your mechanic been there? It would be my guess that he's probably got a pretty good idea of historically what parts he'll be needing per year. We use a program called ManagerPlus which allows us to look back over the past year, or any other year and generate a report of total parts used. I would be willing to bet that his parts list is a summary of the parts he orders over and over and over....some parts are just like that. I think the engineers call them "planned wear items".
