For me, I like having all the plumbing and such done. I think if the rear window really becomes an issue for me, I may measure that CCD rear window at rally or informal meeting (maybe even at the dealer) and decide if I want the service folks at the factory to install it. From what I understand there are a bunch of things that can't be introduced into the production model they have that can be done at the service center. It makes sense that as they build 25 a week to keep up the pace, they have to have somewhat of a cookie cutter mentatlity or each unit would take 2x as long....still that CCD rear window being functional and all is really sweet!
