From what I've seen so far he's got..
900 vert
9-3 Monte Carlo
9-3 Viggen (in bad shape)

Yes @vo940 - I got lucky with that cheap (nearly free!) 9-5.
Thread here. It was a lucky buy and has gone well for the last 4k ish, but it really needs some time spending on it now, rear suspension has sagged massively, it spots a bit of oil (pan or maybe an oil seal), it blew a coupe of vac hoses lately and wife reported something that sounds like ABS module on the way out. And it needs some general love aesthetically. So, cheap is always cheap for a reason..
And unfortunately I spent up fixing the XC90! So this will be a slow game..

I can see why you want to change the wheels. There should be plenty of those more everyday 3-spokes around, I don't think they're rare at all. And everyone wants Super Aero's.
Try Steve @ SaabSalvage in Sydney, otherwise I always hear good things about JB Prestige in Melbourne - he's usually happy to chat so might also be able to point you the right way.
