In a wholly original move, I'll put my hand up as having a BSM 130i in Melbourne too.
If it was 4 months ago, you might have purchased the 130i I was thinking about getting at BMW Melbourne - sun roof and cream interior? I ended up getting one a couple of months later in Sydney and driving it down which was a nice little getting to know you.
I'm not sure I've actually seen another black one, despite how many posts there are here. I do regularly see a silver one zipping up and down Hoddle st in the mornings though.
