Graphite Gray was available on 2004 - 2005 models. Machine Gray was available on model years 2006 - 2008. Lots of paint suppliers state the colors are identical and it only was a name change. But the tint codes are different: Graphite Gray = PDR/759; Machine Gray = PDR/184.

Can't recall ever seeing a Machine Gray XFire with the Dark Gray/Canyon Red interior. That would be rare. Might have been a 2008 model since Chrysler was installing the "salmon" 2-tone interior in a lot of the cars produced near the end of production.

For me, the rarest color combo I saw was an Oyster Gold Roadster with the Tuxedo (Dark Gray / Cool Vanilla) leather interior. I've only see one and it was during the original CAA event held in St Louis. Car was absolutely beautiful! Frank - Do you remember who owned that car? I recall he was member of the St Louis owners group.
