The author - a renowned Porsche historian and author - has produced his third Collector's Guide to the coveted 911 series of cars, bringing the 42-year story through to the latest derivatives. Having traced the design, production and competition histories of this iconic German car (firstly from 1963 to 1980, and then from 1981 to 1994) Michael Cotton in his third volume has carried the story forward to embrace the models from the immediate past and present, culminating in the current designs which carry Porsche's own code number 997. Full production figures, model identities and technical specifications are included amongst the comprehensive appendices which support the main text.
