Why Citroen… A great book.
Why Citroen was published back in 1977 by JP Chassin. As far as I can tell, it’s out of print and pretty hard to find. One of my Citroen Forum friends Mark L. Bardenwerper, Sr. scanned the whole book and shared it with the forum. It’s a great resource for information and how-to help. Click the link to download the PDF.
