Trabi's used to get unbarable Hot in the Summer since they had no AC... or fans most of the time... So a Conversion kit was offered to turn your Trabi into a Cabrio!
I would love to see it get NCAP tested. It would probably do similarly to a roofed one since all structure is in the frames but the driver would just fall out.
Looks much better than a regular trabant, still depressed but summer depressed.
