Good internet resource for Nissan?

Anyone have a good internet resource for Nissan cars? Specifically, i'm interested in the American market 200SX w/ the V6 engine. One has sprung up for sale right down the street from my house. 1987. Black. Super clean on the outside. Couldn't get a good look at the interior, because it was dark out... going back in the daylight for a better look.
Wanted to research this model a little more, and would really appreciate any links anyone could provide. The usual search engines are coming up short... and Nissan's internationally confused marketing scheme (naming the same car different things throughout the world, and naming different cars the same thing) isn't helping!
Thanks.
