I have ordered an S3 with the panorama roof. Today I had my first sit inside an A3 with the roof. I did this because I wanted to be sure that it didn't impinge into my head space (it doesn't), but what struck me was the perforated blind, rather than a "normal" sliding bit of solid stuff. Admittedly it was a warm Sydney summer day (34C) but the heat coming through that blind was impressive. Does anyone from a warm climate (that probably wipes out most of the forum, sorry chaps) have any experience of this roof. How does it work in practice. I am torn on this as I really want the roof, but I really dont want to cook in the car. help please.
