Don't let anyone touch your alignment except BMW. It takes 1.5 hours to align with weights in the front seats/rear seats etc. Highly specialized process. (not a Holden)
Cost at BMW: $95 incl wheel balance at kloster in Newcastle.
At your local joe-blow: $55 plus extra for wheel balance. And they are guaranteed to fuck it up.
I speak from my own experience.
