Randy Leffingwell’s gorgeous new book, Porsche 911: 50 Years...........

Ultimately this is a brainy book for anyone who thinks he knows a thing about the Porsche 911. As the introduction states: “What you read here may contradict what you know about Porsche 911 history. Some of this information was simply not available before now.”
