I remember in the mid 80`s borrowing a friends early A reg BX and experiencing a "road to Damascus" type conversion.
From the brilliant satellite pod controls to the trick suspension to the switch like brakes this was a car totally free of conventional thinking. But what was really impressive was that it actually was better, decisively better, than the humdrum cars of the day.
Citroen, if you recapture that spirit today, you wont need to produce macho supercars or over blown design studies.
Happy birthday anyway
