When I worked in Liverpool a number of years back, one of the guys left his company car on his drive with the engine running. Popped back in to pick up his wallet and someone drove off in the car with over £20,000 worth of various test equipment in the boot. Reported it to police who told him he could be charged with leaving a vehicle unattended and the insurance simply refused to pay out. Car was eventually found burnt out, (including the equipment which didn't appear to have been discovered in the boot), so the total cost was over £40,000
