Hi kapsu
no, although we had (!) several tuners which offered kits, or rebuilt Roccos to convertibles, they are quite rare in germany.
Afaik there is no tuner left who offers a convertible-kit for our Roccos.
In the german forum are only 5 or 6 of them.
What I forgot:
My all-day ride is a 1992 Scorpio station wagon, 2,9 V6
