Interesting - you may have just seen the post on my thread about a new member who apparently has an NG 9-5 with a subframe made of cheese. I thought they were completely NLA.
While you are wandering around is you see a front towing eye cover for an NG, 12823501, which I need because mine fell off after the breakdown, or an airbox to turbo inlet pipe for a 2.0 petrol, 55560898, NLA from Vauxhall and very expensive from Saab, (if available) I would be quite interested, but please don't go out of your way looking.
