Rare, mint and original.
Julius Weitmann (Author), Rico Steinemann (Author)Project 928: A Development History of the Porsche 928
Theres only one on Amazon and it looks mint and original.☺.
If you wanted to see how the 928 came about then its well worth it.
Quite a rare book this. Expensive and hard to find in good condition. It contains pictures of prototypes, test information and design history which simply dont exist anywhere else.
