Porsche Briefly Discontinued the Sale of the Boxster (And Possibly the Cayman too) in the US From the 2005 - 2012 Model Years, Meaning for a Brief (And Pretty Long) Period of time, if you wanted a Brand New Porsche in the US It had to be a SUV or you had to pony up the extra cash for a Base Model 911.
Although this could just be a rumor, i'm going off copart listings and there's a Gap between 2004 (Gen 1) and 2013 (Gen 3).
EDIT: Ignore all that, I'm Looking at ebay right now and the first thing that pops up are 2005 - 2012 Boxsters, Either people barely bought it or hot damn people maintain these things like they are their babies.
