Hi Chaps
If you look at the Bijou and the Citroed DS you will see that Citroen were trying to make the 2 CV Bijou look like a DS and failed. The boot lid and rear lights/bumper and rear wheel arches, The Steering wheel, The profile of the side doors and windows, and to some extent the bonnet line are similar, but on such a short vehicle it does not work as well as on the DS.
I expect that if it had been a success in the UK they would have rolled it out into France, but with the higher cost, lower performance and presumably unfamiliar method of production, it never took off, but is definitely a collectors item.
With an uprated engine, a GRP body and some TLC it would make a great little car to own.
