Very Nice Minerva's, heres my '79. Yes, the sunroof was an option up to '87 I believe, when it would've turned into a delete. All three of my turbos show the sunroof as an option, either on the COA, window sticker, or option sticker. The '79's sticker shows "electric sliding roof" as a $795.00 option.
I think Porsche/VW North America specified all US cars have this "option" unless otherwise ordered off. I think the culture of these cars on both sides of the Atlantic were very different. Euros have always put an emphasis on the driver oriented experience while in the US it's been about the amenities and driving the car thru valet. Yes this is a generalization. US cars got A/C as as standard equip while in RoWs cars it was an option. I think Porsche NA thought these "options" either standard or not were a must when selling a $30-$45k porsche. My '77 has only one pricey option and that's the sunroof, no limited slip, sport seats, or even right side mirror.
