All car enthusiasts know about Shelby Mustangs, but what really separates them from their production-line relatives? What really makes a Shelby a Shelby? This new book from Shelby American Auto Club (SAAC) historian and registrar Greg Kolasa details the specifics on the performance and appearance alterations with both descriptive text and superb photographs. This book gives a detailed look at both the performance and styling characteristics of each year of the 1965-1970 Shelby Mustangs in text, photographs, and charts/graphs and clears up many myths and misconceptions surrounding these legendary pony cars. In addition to his firsthand knowledge, Kolasa relies heavily on factory documentation and interviews with Shelby American designers, engineers, stylists, fabricators, and race drivers to get the true, as-it-happened story of these phenomenal pony cars. Additionally, the cars included in the book were chosen specifically for their historical and technical "correctness." The Definitive Shelby Mustang Guide: 1965-1970 will serve as the illustrated Shelby Mustang sourcebook for years to come. For Mustang and Shelby enthusiasts especially, but even for general automotive historians, no automotive library would be complete without it.
