I must admit and i aint just saying this because i have a plastic window, but i think the "softtop" should always stay plastic window, ferrari have said this for years...
plastic all the way for.. although the glass window wont mark and can be tinited i think the shape looks strange...
dont bite my head off as i am sure people will disagree but i wouldnt go for a glass rear window, i just think plastic looks superb and really add to the shape of the car, i just hate the idea of glass windows inside soft tops.
i didnt think the 03 boxster had glass windows... thats news to me..
remember boxster rpices have fallen in the second hand market due to people handing them back to the higher purchase company and with the new 987 this wont help..
