Like i said before, I've been looking for a while. It's almost impossible to find a white calais with the bone interior (out of the hundreds i've seen on carsales, i've come across one - it had about 130k on it though). White looks really classy, though you'd have to live with the black interior unless you were REALLY lucky.
As hingo said before, one did sell in Canberra on the weekend. I went to look at it in Phillip on Saturday, but i was too late. It was silver with HBD sunroof. The salesman told me a guy from Perth bought it, just paid for it and asked them to send it over on a truck. He didn't even look at it, was very tidy though. I had a good look over it. Had about 75k with the 5.7L engine. It was only on carsales for a couple of days, that's how the bloke bought it.
When i was looking for a Mazda 6, there was only one that met all my criteria. I had to go to Shepparton to get it - even though it's a nuicance to change over the rego etc. I would have been disappointed if i'd settled for something less.
I've got my name down at a few dealers in Canberra if they manage to come across one. I might suggest doing the same - as well as all the options everyone else has supplied you with.
