Citroën Ami 6

A small Citroën with a reverse-raked rear window, so that the back seat fitted under the roof.
The Ami 6 was to sit between the 2CV and the DS. Its shape was controversial, but it became one of France's best-selling cars of the 1960s.
Materials: Steel body; two-cylinder engine from the 2CV
Manufacture: Made in Rennes.
The rear window that slopes forwards instead of backwards.
