Original Mustang 1964.5-1966 takes the most ideal approach to the subject. Focusing exclusively on the first 2.5 model years, Mr. Date is able to focus his efforts. The photos are varied and of high quality, and tend to be of unrestored california cars - offering unprecedented insight into originality. This is a refreshing approach as mustang originality can be a difficult thing to pin down.

There is extensive info on VIN decoding, color options, etc., much of which is admittedly widely available, but if I were able to have only one mustang book, this would be the one.
