The Citroën 2CV had many official special versions, many of which were only locally available. In Germany the 2CV was nicknamed 'Ente' (duck) and probably only a fraction of people that knew the 'Ente' actually knew it was made by Citroën! i remeber two special versions that used the nickname:
The 'Sausss-Ente'


and the 'I fly bleifrei' (bleifrei means lead-free)
