I am in the market for some manuals/literature to furnish the new
workshop, what do you guys think of the following:
-Mitchells manuals
-Mitchells on Demand CD
-Alldata CD collection
-Chiltons
-Regular professional / factory manuals from Helms
or any others for suggestion, pros & cons
ohh and how can I obtain some TSB ??
