A 1950 Cabriolet has just turned up on Ebay in Germany.https://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=p It will be interesting to see what it goes for.
Interesting, it's an Austro- Tatra conversion, not a Karmann...
I take it that it is extremely rare and quite valuable.
...or a scam?
Look's Like Someone Bought it !
