don't think you'll get down to 90k, cheapest i've heard was 94k on corporate, but i think most people got it for between 95-100k.
you'll also be looking at a 6 month wait depending on the dealer.
RACV has the CLA on thier online quote system now, mine came in at 2.2k/year, yet to get one from Merc (Allianz)
the corp programme also comes with 4 years roadside included.
