A group of related sites is fine with me. Doesn't matter where the stuff is as long as one can find it. On tools: Specific Porsche tools are on Pelican and more generalized are on Drivewerks, But I guess a search will take you to where it is located. Must be tough to draw the line when choosing which site to list items like tools.
But with 3 divisions, I can only anticipate 'Ferrari Emporium" as a 4th.
