Recommended reading.
The following list of publications are, through my experience, worth seeking out. I am sure that there are many more, so if you feel that a title should be added please let me know. It should of course be noted that the Bentley Drivers Club output of "Reviews" and "Technical Facts - The Vintage Bentley" are of considerable interest. Those winter evenings will fly by!
