If you were able to order your 1965 Imperial new at your local dealership, your ever-friendly salesman likely would have sat down with you and paged through one of these books with you. They typically show some of the major options and option groups available for each model line along with some photos. They were not meant to be a "complete" list of options, and since they were printed just as the new model year began these books do contain some errors at times.
Like just about everything here at HH, this section will be a work in progress and other data books will be added as time goes on.

Special thanks to SuperB & Doug Hammer! SuperB let Doug borrow this book so he could scan it for us, thanks guys!
