I was told by my now long gone local Chrysler dealer that only charcoal (black) and charcoal/grey interiors came into UK because that's UK buyers want.
The UK market is not receptive to the brighter more adventurous interiors that the USA market likes. These were only available special order, hence very few here. Thats why we got no Alabaster White or Oyster Gold Crossfires, they were just too exciting for us Brits to own!
Its not just Chrysler; look any any brand of car you will see the same trend, different colours for different markets all chosen by market researchers
