This book covers most everything garage mechanics would tackle in their garages.  The directions seem well written.  I have referenced it a couple of times, and it helped out.  The instructions can be a bit short though, and they tend to lack some details.  Navigating the book can be really annoying.  Some instructions stop mid-way, and direct you to a different part of the book.  When looking for something specific, I have ended up flipping through the whole book looking for the directions.
