Query: Shelby book review

I purchased the soft cover instead of the hard. As long as you don't abuse, it will last & you can save a great deal.The contents are very good in tracing the history of Carroll Shelby's "creations." Illustrations are awesome and the book is a must for Shelby lovers. I myself have a tribute 2006 GT350 modified with the features and appearance of the late 1960's Shelbys
