The address for the website is:
www.porsche-cayman.se But you have to enter a personal promotional code to be able to enter. The site in itself isn't very interesting, no pics or anything, just a some questions you have to answer to get the book.
After answering the questions they said the "book" would be on it's way home to me. I'm hoping it will be a thick book about the car, but it might just as well be the booklet. Maybe they're calling it a book to make it sound more fancy... It's only avaliable in a limited number of copies though. I'll let you know what it is when it reaches my mail box.
