I know the VW arena is a lot bigger worldwide than jtin, but i always dig this section at The Samba:http://www.thesamba.com/vw/archives/info/
I see things floating around here and there on the forum, but it would be kind of cool to have something a bit more organized on the tech side of things. I know there is a japanese site with 20 million brochures, but still. Would be a good reference and help the genre overall, i think, for noobs and experienced alike. Might take years to build...Just an idea!
