For those wanting to upgrade their exec or berlina interior here are the parts you're gonna need. GM-92141522 chrome auto shifter button GM-92145498 anthracite leather auto shifter GM-92145148 anthracite leather handbrake cover GM-92142530 chrome handbrake button GM-92142529 chrome bezel around handbrake button GM-92092090 VX Calais Series 2 upper dash fascia (silver) GM-92092087 VX Calais Series 2 lower console part (silver) GM-92102401 anthracite leather centre console armrest GM-92046999 Fog lights switch and bezel. You'll need the switch and bezel otherwise you'll have a hole in your dash as holden don't make plastic blanks to fill the hole, or just get fog lights.
Seats? Just get them out of a wreck. The calais seats have power back and forward where berlina and exec have the bar to move them so I don't know how you'd hook it up. The velour seats in my berlina are good enough so I'm not looking at replacing them, so no part number.
