Got my SMS for collection! After initially logging in and being told slots were full (presumably the Monday got opened up first), seems they've opened up for Tuesday in Melbourne as well. So Tuesday afternoon it is! Looking forward to it.
Despite some niggling delays in the past couple of weeks, it has been pretty smooth sailing the whole way in my experience - from ordering, to registration, to payment, through to collection.
Now to finalise the insurance.
Good luck to those still waiting around the country. Thanks in particular for those who have contributed insights to me thus far.
I'll see you around this forum (in other pages), but otherwise look out on the road for a smiling driver in a Black/Black M3 Long Range if you're in Melbourne!
