There have been some really nice tutorials of various mechanical fixes on this site with some nice pictures included. What would really be helpful is an area where specifications like bolt torque values are listed as well as other pertinent information needed to do such projects such as clearances etc. Not everyone has the access to the wis or what ever it called. I thought I read someplace that there is a Mercedes technical website that you can pay a certain amount to see the info. A nice link to that would be nice as well.
