They're all second hand books off yahoo auctions in japan... one of the benefits of working for an importer with an office in japan to have stuff delivered to You'd pay more though if you used one of the backyard parts importers with their profit margins, agent fees and all that.

Dorikin_Yakuza, $25 was for all the books that I posted pics for in the first post.

I wish there were scans of the AE86 Bible somewhere though, as I'm dying to buy the book, but I'm not sure if its worth as much as people ask for them if the content has already been covered in what I've got.

You can order some of the books from Amazon Japan too (think the Hyper Rev one is available there), but they only deliver brand new books internationally, and most of the good ones are second hand.
