I need the shop manual of my car to do a better mechanical job.

Bentley or Haynes do Mini manuals on amazon, etc.

Not sure if this download of the factory manual is still working:

Link to NAM:
Service Manual Download Link MINI 02-06 - Forums (http://forum.minicooper.org/showthread.php?t=15737)

But its a megaupload link and .. sadly the f.b.i Shut down thaht web site a month ago.
