Citroën Berlingo Multispace 

The Berlingo Multispace is available with a sliding rear side door - unfortunately only on left hand drive versions which means that Britain, Ireland and other countries that drive on the left won't see this particular model.  Update May 2000 - the Berlingo is now available with twin sliding doors.

With its full length sunroof, the Berlingo Multispace is bound to draw comparisons with the 2 CV.
