OK, I've found what I was looking for:

http://www.volkswagen-vans.co.uk/index.php?
action=downloads.downloadPDF&model=california&file=california_brochure

It's a very nice document decribing the California, including lots of nice
pictures and technical spect (even power output of stove!). You'll need a
PDF viewer such as Adobe Acrobat for that one.

And for the web page from which you can wander around for more info:
http://www.volkswagen-vans.co.uk/index.php?action=california.main
enjoy!
