Hey sorry to here about your car man, cops in this country suck, they hate cars like ours and the guys that drive them so im not surprised that they didnt give a crap. Bet the guy that stole it prob lives down you street if not very close.
If its of any use you could try contacting a insurance lawyer, they are very very very good at getting insurance company's to pay out what its insured for.
I keep mine in a garage and i have a angry dog..... good insurance policy which cost half a tin of dog food a day.
