I think you're probably right. The headlamp shape leads me to believe that the blue car is a Citroen Xanae prototype (http://www.citroenet.org.uk/prototypes/xanae/xanae.html), an MPV prototype/predecessor for the Picasso.

Thanks for pointing out, I edited my comment to show the mistake. The article text above it and graininess of the photos really seemed to make them from 1980 :/

One dead giveaway are the A-pillars. Manufacturers back in the day didn't imagine we would have side curtains and double reinforcements in pillars today.
