usually from ONLINE toyota dealers.

they aint like stuff you'd find on amazon.

one cool thing is toyota has a tech info online where you can download PDF files of the manuals. but there are TONS of individual files to download.,

you pay like $20 for like a 2-3 day subscription fees.

these are mainly for repair shops where they maintain a yearly subscriptions.

funny story. when i got my subaru STi, a bulletin board started a project that wrote a script to download the whole PDF files.

it ended like over 150 separate files...

for my set, i bought it from a texas toyota dealer. ended up like over $200.

well worth it. came in 5 volumes.
