cabrio time

i heard that 15 cabrios were made – as prototypes…
 
where the F*CK are they now?
 
i know of three:
one in the wolfsburg museum (red one)
one in the Karmann museum (white one)
one scrapped years ago in Bielefeld, Germany
(had an Oettinger-Okrasa engine!)
 
seems they came in red,white or blue…
keep me posted !
