Marko,
Not trying to be disagreeable, but my 1982 base Mirada has the fake woodgrain (now slowly fading to pink, and the cracked door tops to match). It is Nightwatch Blue exterior, blue interior with cloth split bench seat. I have seen a few other Miradas with the fake wood, and a couple with the aluminum dash. Door tops on those with the aluminum dash are the same colour as the interior. I don't know for sure, but the fake wood may not be a specific option, but part of some option group, or it may be part of the split bench package. Just to be clear, this is the factory interior as far as I can tell, and the car is pretty much loaded.
My 1981 Mirada CMX has the painted sliver/aluminum dash. It is a bucket seat/console shift car in red, with the white vinyl fake convertible top.
My 1980 Cordoba has the wood dash. It is a cloth split bench car in cashmere (Chrysler's name for a light tan colour).
