Volume One traces the history of Opel and Vauxhall separately from inception through to the 1970s and thereafter collectively to 2015. Special attention is devoted to examining innovative engineering features and the role Opel has taken of providing global platforms for GM. Each model is examined individually and supplemented by exhaustive supporting specification tables. The fascinating history of Saab and Lotus begins with their humble beginnings and examines each model in detail and looks at why these unusual marques came under the GM Banner. Included is a penetrating review of Saab through to its unfortunate demise. Volume Two examines unique models and variations of Chevrolet and Buick manufactured in the Southern Hemisphere and Asia but never offered in North America. Daewoo, Wuling and Baojun are other Asian brands covered in detail. This volume concludes with recording the remarkable early success of Holden and its continued independence through to today. Volume Three covers the smaller assembly operations around the world and the evolution of GM's export operations. A brief history of Isuzu, Subaru and Suzuki looks at the three minority interests GM held in Asia. The GM North American model specifications are the most comprehensive to be found in a single book. Global and regional sales statistics are included. GM executives and management from around the globe are listed with the roles they held. An index ensures that these volumes serve as the ideal reference source on GM.
