Dear friends, it's me that should thank you. And not only for the big help you give me, but also for the very nice experience of discussing, comparing sources, discovering new info and checking a lot of things before printing the book.
I think we can consider it as a "book 2.0" because of the way it has been put togheter.
And I hope this time I will minimize that ugly phenomenon that afflicts every author when a book is already printed: dozens of friends sending mails like "I forgot to tell you about that coachbuilder..." or "why haven't you asked me: I've plenty of unpublished pictures..." and so on.
