Query: Only good for a few models

As the others have said, this book is not very good. I found one by Haynes which is much better; for example, I used it for a 626, a very popular model. The Chilton's was dead wrong in some areas and very poor in most others. The Haynes was dead ON in all areas I needed. That seems to be true for the whole book; forget the chilton's (which has been an excellent source in the past for these kinds of manuals), and, in this case at least, buy the Haynes, which is also cheaper, by the way!
