This is a 2005 N\A white ltd. It had this when we purchased it. It can be opened to any position or closed but the rear is open. The sun filter can be shut in either open sunroof or closed sunroof. I have no idea who did the install, but it is flawless for aftermarket. Personally I would have never cut the spine. I have to say it is pretty nice to drive it with an open top and a manual trans. What do you all think about this?
