I am VERY interested in this group buy. I have had my 2007 Roadster since 2011 and have been dreading the day that my rear window fell out. That day happened suddenly yesterday. The window appeared to have been perfectly fine the day before, but when I walked up behind it, I noticed the top was sagging and the window was detached along the side and partially on top. Luckily it happened on one of the few days it hasn't rained. Needless to say I am sick about this, especially after researching the costs of replacement, so this potentential group buy would be a godsend.
