"Below is the post from
www.ppbb.com for a possible source of the strataglass. Searching this forum and
www.renntech.org, you can find posts where Boxsters owners found a upholsterer or a top installer willing and able to install the window. Off the top of my head, it seems that range for the installation is $300 to $600 dollars. Sadly, not cheap but cheaper than a new top and installation."
Thanks for the info, I will consider it, but it looks like there is going to be a lot of top-down driving for me, at least for the near future.
