Here's a zipped word document I cobbled together from all the available prize car, race info and complete car lists available on GTPlanet. It's now formatted so you can see what to win where. Pages 26 onwards have the complete car list, based on the original Japanese lists, with NTSC notes where appropriate.
If you print the first 25 pages out, then load the paper appropriately into your printer so it prints on the back of the previous pages (test out proper orientation on a single sheet first
) then you should get the complete race requirements, prize car, prize money and complete list printed in double sided form in 25 pages.
I keep a printed copy so I can check off which races I've done, which cars I've collected, and which cars I've actually driven.
Hope this helps.
