I CAN change insurance companies, but I don't know if any of the normal local ones will be any better. I will look into it soon, actually, because it's nearly time to renew, but it's such a pain and the chances are that nobody will actually cover the empeg. The car is worth about half as much as the empeg, apparently. Yeah it's a bit of a shitbox (I wonder if that will get censored) but I've decided I'm not getting a new car until either I pay off the house, or the old car gives up the ghost. Besides, I've grown quite attached to it. :)
Maybe I should ask a local car audio shop, they might know of specialist policies that are used in these situations.
