here is a little story (and yes i am insured) after a problem which left me unable to drive for 2 years i was finaly cleared to drive again (i'm registered disabled so its an automatic), i dont have a motobility car its my own so i rang around several insurance companies trying to get cover for my (then) 5 year old car (fsh mot etc) most companies wouldnt touch me the minute i said i was disabled, those who would wanted to charge me more than the value of the car (at that time) and none would allow me any of my former full no claims bonus, i decided not to bother with insurance, sold the car and took to using taxi's and the access bus, six months later i decided that i needed a car so i bought a new one it was a reasonably sporty one ( i like to know if i put my foot down i'm going to be able to drive out of trouble) again i applied for insurance (accidently failing to tell them i was disabled as i could legaly drive an un adapted car as long as it was an automatic) now if i told you they wanted £2000 a year for third party when i had a car worth about £2000 and told them i was disabled i was extremely suprised to discover they would insure me fully comp on the new car for around £1000, what is worse is that when i shortly after informed them i was disabled they actualy gave me a partial refund on the original cost, so what changed?
i moved house which could have made a difference, but it was within the same postcode area, was it because my car was less sporty ? i went from a cavalier 1.6i to a nissan primera rallysport so i dont think so, was it where it was parked? old house alarmed garage, new house driveway so no that couldnt be it either, maybe it was the security? old car full thatchem alarm and immobiliser and tracker, new car same kit so not that, out of interest i called the company back and asked them i got some bull back but from what i gather at times of higher new car sales they charge less for a few weeks to try to attract new customers with new cars.
the moral seems to be insure your car just as the new registrations start and you can save 50% on your insurance. (oh and for what its worth i still hold a stage 1 rally licence and an advanced drivers certificate).
odd thing is, my dad is over 90, was an apalling driver (cant drive now since he had a stroke

) yet his insurance on a similar priced car to mine was only £450 fully comp.
Personaly i think they just play think of a number, make it as high as they think they can get away with, then if you ever do have an accident it seems they screw you as much as they possibly can.
if i thought i could get away with it i must admit i'd think twice about getting insurance. (probably still would on grounds of conscience though if i'm being honest)
