Mate, there are 2001 and 2002 X5's in Vic for $9000.
Its nuts!
Some with only 150,000k's

Yep, they depreciate so hard, you only have to look at BMW 7 series of the same era to see the amazing value these vehicles represent to second hand buyers.

I'm not sure what you mean about "not selling at the moment"... Its never going to get any better.
