AAMI was $400 cheaper than my quote from NRMA. NRMA quote was then $150 cheaper than Suncorp (who I am with now and I have multiple policy discount).
Needless to say I am not staying with Suncorp. I am thinking of switching to NRMA. I don't want to go to AAMI (despite the cheap price tag) because you don't have a choice of repairer and I hear AAMI is terrible to deal with on a claim.
