The thread about a Mini Van in USA posted today had a link to MiniMania, which had a link to the following website. I've just spent an hour trawling through the various pictures. An amazing Mini enthusiast website that you might also find interesting. A search shows it has been referenced previously on Ausmini but some time ago, so I thought it worth refreshing.
It contains photos and in some cases downloadable copies of:
1. Sales brochures
2. Mini models
3. Advertisements
4. Books
5. Cutaways
... and more.
