Personally, the Dark Slate Gray interior looks really good with the Oyster Gold.

I was shopping for one several months back and found a lot of 2008 Oyster Gold XFires with the Dark Slate Gray/Cedar 2-tone interior. I don't think this combo looks particularly good. Looked like Chrysler had quite a few of the Gray/Cedar interiors left over near the end and put them in just about anything that came down the Karmann line.

Now the 2-tone Dark Slate Gray/Vanilla combo in an Oyster Gold XFire (as reported earlier in this thread by Sonza) has got to be rare. I've never seen this setup in all the cars I've looked at.
