limit the milage to as low as you dare, put your mum on the policy as a named driver (i got quoted 2k for a wrx impreza and got it down to 1200 when i put my mum on it) and if you can put the value to as little as possible if you are insuring fully comp if not and you are going third party tell em its worth fook all
if it makes you feel any better im currently payiing 110 quid a year for a s3
