I have three 928 shop manuals for sale, that came with an '80 928 I used to own. I have no use for them any longer, and would like to sell. I have Volume 2 (Transmission), 3 (Chassis, Heating, Air Conditioning), and 4 (Body, Electrics). Overall, each manual is in good condition. The only damage I can note, is some water damage to Volume 4. A few pages are sticking together at the bottom, but they should come apart easily (I got several unstuck, without issue). Copyright date on each is 1977.
I'd like to sell the three manuals as a set. Asking $125 shipped, for the three manuals.
