   Most of what auto repair people do is to figure out which
   subassembly the funny noise is coming from, then replace the whole
   thing.  No?

Sure.  But that's like wrapping a shell script around your X server;
anybody with "mechanic's feel" can do it without have internal manuals 
or source.

True; but the kinds of things you mention are exactly the things that
a layman can do, and do not require access to source or auto-specific
expertise, only that "mechanic's feel."  Let alone knowledge about the 
specific make and model.

More reasons to dislike this analogy; there are just too many places
for it to go wrong or be irrelevant.
