I’ve used Haynes manuals over the years and always thought them to be one of the better non-manufacturer manuals.
I recently purchased this manual so I could maintain my 2008 Legacy 3.0R Limited and was disgusted to find on the inside cover that it didn’t include any six cylinder specific information. It would have been great if that fact had been advertised in Amazon’s listing and even better if it’d been on the cover of the book. Now I have a book that will be largely useless for anything that involves the engine or is specific to the 3.0R model.
As another reviewer noted, the book is overly broad and covers too many models and years. Photographs and diagrams are frequently not helpful or missing and I found myself using my iPad to research tasks which should have been clearly described in the book. A good example of this is something simple like changing the cabin air filter. The book has you hopping back and forth looking for information, but never clearly shows the information.
I’ve had Haynes books about other vehicles and this one isn’t as good as some. I’ve found sections that I’m interested in that don’t have enough detail or photos to suit me. It seems that this book tries to cover too broad a range of vehicles and suffers for it.
This is perfect investment for anyone who needs to know how to do anything for their car. Perfect for the car junkie.
