Thanks, it is a bit disconcerting to think, that the CX, came out in 1974 - it still looks modern. I don't believe that the CX was ever officially exported to the US. However, I'm sure, a private firm did try to import them. It wasn't really going to work - one of the things that had to be changed, to comply with US regulations, were the headlights. Replacing the carefully deisigned aerodynamic lights with four round sealed-beam units, spoilt the effect somewhat.
I think Citroen's latest designs, the C4 & C6, are taking their styling back to the fore. The C6, in particular, is a superb looking car.
I've also got the Minichamps CX Prestige - built on a longer wheelbase than the normal car - I'll try & post it along with the SM - one of my favourite cars of all.
