Transparent

Another day spent in Maison MD - it was raining outside, snd we were waiting for deliveries (a downside of self-isolation).
Looking for a Blip I came across this transparent car.
It's a Citroen XM made out of a block of clear acrylic plastic.  At the launch of the XM in 1989 every dealer was given one.  I wonder how many there are still in existence.....
