I was wondering if anyone has a set of four hubcaps for sale. I believe my French "Image" model is similar to the UK "Meteor", but since I've heard that those trims fall off if you so much as look at them, I don't imagine there are many still around - so any original BX ones would be great, since my local scrap heap has drawn a total blank, as has ebay.
I still have a UK bank account, so payment would be dead easy.
Good luck - OE wheel trims seem to be a very rare & sought after comodity. Have you tried eBay.co.uk/.fr? Sometimes odd ones turn up on there.
Mine currently sports Berlingo Multispace wheel trims. Not OE to the BX, but Citroen at least. I think they look quite good on the BX.
