I believe they just stopped making new bugs in mexico, but i'm not totally sure, i think they finished with something called the millenium edition in 2000. You could sure as heck find one used though.
and i'f you're interested i've got a 56 oval ragtop shell, they're rare as hell, but it's been crashed into, i've got a replace ment door and quarter panel, and the a replacement front clip was crappily welded on there, i was gonna do one of those fenderless hot-rod bugs when my z is done, and that elimintes the front half of the front clip anyways, they do go for big bucks once they're restored though... pm me if you're still interested.
