I'm 21 and my G6ET costs just over $1,400 (Full Comprehensive with Windscreen Option) with an $800 excess (plus another $400 age excess for any under 25 driver including me). I live near Parramatta in NSW. I actually found it was only the mainstream ones who were willing to insure it for a reasonable dollar value or at all. Basically, NRMA, AAMI, Allianz came out reasonably well, all would cover me. The only non-mainstream that would cover me was Just Car and Shannon's would too but their premium was over $7,000. Of the non-mainstreams I tried, I actually got given (deadly serious) a quote of $14,500 or thereabouts for Comprehensive from one insurer. However, other than this absurd one, the Shannon's one and Just Car, no other mainstream insurer would touch me with a ten foot pole. I even tried Woolworths and the quote was OK and when I rang up to enquire what the go was with quotes the guy got all panicked because it should have auto rejected all turbo cars, lol.
