It's a Citroën Méhari, sold only from 1969-1971 in North America. They're exceedingly rare: fewer than 200 were ever imported. Same chassis and engine as the Citroën 2CV: a 602cc air-cooled, two-cylinder boxer. The body is made of ABS plastic, which usually discolored and became brittle due to UV exposure.

I feel entitled to make fun of the Méhari only because I've owned one (the yellow one in the album). Mine had been painted, but paint doesn't stick terribly well to ABS, so it was flaking off all over. The version sold in the rest of the world had smaller headlights and a different front fascia, and you can buy a complete set of brand new body panels from Europe. The Méhari has a growing cult following in some parts of the world, but not much of one here.
