Collector's Originality Guide Porsche 911
While this book is everything one would expect from the title, what should be made clear at the outset is that is a word-for-word reprint of the book "Original Porsche 911" by Peter Morgan originally published in 1995. As far as I can tell, the only things that have changed in this newer edition are the organization of the Table of Contents into chapters, somewhat improved reproduction of the photographs and an easier-to-read font used to caption those photographs.
In other words, if you already own the earlier version it's really not worth the $29 to purchase the reprint.
