Downtown Seattle, there is a bookstore named Kinokuniya, it's all Japanese books, magazines, CDs. They carry both
J's Tipo and
Nostalgic Hero the Japanese mags that most often have 1200s in them. A bit expensive (about $9 USD, or about twice what a domestic magazine cost). They will also get subscriptions for you at a bit of a discount.
Seattle's not a mega city (pop only 470k), but the whole Seattle-Tacoma metro area is about 3M, so that's a good size and we get a fair selection of international stuff. Rumor has it there are half-dozen illegal Skylines running around here. There are also reportedly 60-70 legal ones in Vancouver, the next big city to the north. Speaking of Prince, the only trouble with Nostalgic Hero is ... it's Prince, Prince, Prince. Every month it seems. The largest Japanese characters on this cover say "Prince" and that cover car is a Prince.
Then at Barnes & Noble they have a couple Aussie mags (Drift and Fast Fours, if I recall). Last month they had the "150th edition" with "Australia's Quickest CA18" in it, a
Datsun 1200 ute owned by Mark Bourne.
