I bought a CD full of MK1 Golf Guides from eBay a few years back. It appears to be a mix-mash of material from different sources (forums, workshop manuals etc), but there is some really good information contained on it.
As I have not created this collection myself or verified any of the contents, I feel it is unfair to pass any of it off as my own. Instead I have provided access to the entire CD.
An online copy (viewable in your browser) is available here. Alternatively, a zip file containing the entire contents of the CD is available here.
Please note that I am unable to take any responsibility for the content contained within this collection. Use of the information is entirely at your own risk.
