$3, 500+ for third party, fire & theft WHEN I turn 21 (a couple of months) here in WA (quoted for an R32 I plan to buy)... That is with a 20% no claims. Three years and I could afford to buy a new one! That is insane... If it doesn't get broken into I am still getting robbed blind...
I guess if the low lifes would stop stealing cars they can't afford because they don't have JOBS, then it wouldn't be so high. My car and my girlfriends were broken into last month in our car-port, less then 3 meter's from where we were sleeping!
I think pentae is pretty much on the ball. Get the best insurance you can afford, the best alarm system, park in the safest possible locations and try not to draw attention to yourself close to home and work, and you lower your risk of being broken into.
Rightly or wrongly though, if they want it, they'll take it. Its a sad situation.
