That's hilarious. The German version (VW Caddy) is similar. Citroen at some point had a van version of the 2CV and the Diane, this is the continuation of that tradition.

Literally: the C15 was based on the Visa (clearly, when you look at it!), and was the first platform-shared vehicle between Citroen and Peugeot where it was basically a Peugeot warmed over with some additional eccentricity. Not bad, overall though.
