Volume four in a series that will become the definitive reference to the Porsche 911, the world's favourite Porsche. This volume continues the story of the 3.2 litre Carrera series, and goes on to cover the 959 production car and the last of the air-cooled 911s. A process of continuous evolution has kept the 911 fresh for nearly 40 years, while impeccable build quality has ensured that most of even the very earliest cars have survived as desirable and usable classics. This is the fourth volume of a set of books which will chronicle in definitive depth the history of the evergreen 911, from the earliest design studies to the water-cooled cars of today.
