Well, in that case perhaps you were expecting Divine Intervention.. What was that song by Janis Joplin that went " Oh, God won't you send me a Mercedes Benz..... My friends all drive Porshes ..... I must make amends....."
I consider the manuals/board relationship to be this:
These are the people who had several score of years experience manufacturing automobiles before your particular car was made...
They wrote from that vantage point. The Board Members have the advantage of hindsight as to what worked right and did not...and ways to fix things which may not be available through Mercedes. They are also more reasonable in terms of cash outlay in their thinking process since they are not making money on the fix.
When I go and read the Actual Manual.... I am impressed by the WARNINGS and the upgrades which are listed there. These are often left off the answers by members due to their orientation of detective/advise on a particular problem. Many of the items in our engines had two or three major changes to them over the life of that style engine.... and they often suggest getting the newer version rather than just replacing the broken part on our engine.
Of course the manual's are pretty dry reading.... I have not detected ANY PLOT yet.... and they certainly don't mention all the beggetting, adultery and violence of the Other Book....
They are wonderful in the COMMANDMENTS section... DO NOT do thus and so OR you will REGRET it. !
And they mean you will REGRET it RIGHT THEN... not in some future lifetime.....
