The book is well organized and easy to read, and contains good detail on just about every rebuild, including transmissions, engine, rear end, brakes, etc. As the cover says: "...Based on a complete teardown and rebuild."
I'm about to embark on a complete teardown and rebuild of a '71 2002, and bought this book to make sure I would have all the information necessary to complete this project. All of the stock BMW carburetion systems are covered, but my car has dual Weber 40 DCOEs (a common aftermarket addition). The excellent "Weber Carburettors Owners Workshop Manual" from Haynes covers them.
After reviewing it, I'm satisified that everything I will need is there, equivalent in content to the BMW and Bentley manuals. I'd give it five stars if the quality of the reproductions were better.
