Hi Overdrive
This was a very timely thread for me as I have had the same issues to face. I have what looks like a puncture in the vinyl on my 2001 S, and the dilemma was whether to (a) have a motor trimmer replace the window, (b) have the insurance company pay for it (if the cost was more than the excess), and (c) whether to go for the larger vinyl or smaller glass, both with pros and cons.
This is what I have - with some tape glue remnants still visible ...
A few other pictures for reference:
I was referred to a specialist motor trimmer by my Porsche mechanic. The quote (parts and labor) for a vinyl replacement was $850 (this is Perth, Australia!) and for a Robbins glass window (full roof) replacement was $2900.
I contacted my insurance guy with some trepidation, although I have been with them for a claim-free 12 years (11 1/2 with a 1957 356a, and just 8 months with this 986), and mentioned only the Robbins glass quote

Well the insurance guy (actually it was a gal) did not turn a hair and said, "that is very reasonable". So I went back to the installer to give my go ahead (pending final approval by the insurance company once paperwork is completed and the above photos looked at).
Reassure me that the Robbins roof plus glass is a good replacement please - having a little pre-purchase anxiety!
