You need 3 of these manuals if you intend working on your car as opposed to just polishing it.
1 To use in the workshop without freaking out should any pages get dirty thumbprints in the heat of doing the work.
2. To keep on your bookshelf and only read indoors when your hands are clean.
3. To remove the cover, separate the pages from the spine, punch holes, keep in a ring binder from which pages can be removed to scan (to provide free info to others) without either breaking the spine of the manual or scanning and having a shadow on part of the page because the full manual won't sit flat on the scanner bed.
