Many of the most popular cars of the muscle era came from General Motors. Spread across the General's various marques were models like the Camaro, Chevelle, GTO, Cutlass, Skylark, Tempest, Impala, Monte Carlo, El Camino, and many others. This book will provide 101 hands-on, how-to projects aimed directly at fans of classic GM muscle, showing them how to do just the kinds of projects that they want to do: restoration of the exterior and interior, and performance upgrades to the engine, driveline, and suspension.The existence of many large aftermarket companies provides evidence of the vast potential audience for this book. Restoration and performance part companies like Year One, National Parts Depot, Summit Racing, Jegs, and Original Parts Group count on this audience to provide a large portion of their business. For example, Original Parts Group, which specializes exclusively in parts for GM A-body muscle cars, sells an average of $100,000 worth of parts each day. Primedia alone has six magazines that serve this crowd (Hot Rod, Car Craft, Chevy High Performance, High Performance Pontiac, Popular Hot Rodding, Super Chevy) with a combined circulation of 1.7 million readers per month.Like the 101 series books before it, this book provides an immense quantity of do-it-yourself projects that are accessible to the at-home mechanic who has a good set of hand tools and a place to work. Procedures will be performed on specific GM cars of this era, which differed more in sheetmetal and trim than in the functional components, which were often similar or identical from car to car.
