Dont forget that the website you refer to is a forum users who's from Belgium (I think) so the special editions will probably refer to euro cars that may not have been seen over here, that's not to say that yours is not a special edition but as far as I know any special edition cabs usually say it on the V5 doc. If you look at the website it says nothing about Sportline or Rivages which were more than likely UK versions rather than euro ones.
