By Randy Leffingwell and David Newhardt. When Ford wanted to add some spice to its new Mustang pony car in the mid-1960's, it turned to a talented, colorful, and opinionated Texan by the name of Carroll Shelby, who was then building high performance racing sports cars (Cobras) using a British body and Ford engine. The resulting Shelby Mustangs proved to be the definitive performance Mustangs of the muscle car era. Includes the most talked about and anticipated version the is the Shelby Cobra GT500, which Ford brought into the market in 2007. Shelby himself was involved in the development of what will be the most powerful factory Mustang ever produced. 192 pages, 200 color & 50 b/w photos. Price each.
