As an insurance adjuster, I must echo a previous post - be sure to get an AGREED VALUE policy, not just a "stated value" policy or some other type. Only if there is an agreement as to the pre-loss value can you be sure to receive that amount in the event of a total loss. Insurance policy limits are ceilings, not guarantees, and most policies state that they will determine the value of the loss at the time of the loss, not to exceed the stated limit. An agreed value policy is just that, an agreement between you and the carrier that the car was worth $XX,XXX.XX. If the car is stolen, etc., that is the amount you will get - no dickering about the condition, value, or anything else.
Also, as the person who has to investigate these losses, do not mess with the rules they set up. I have seen people make material misrepresentations on the information they provide on the application, or during a claim, and it may void the entire policy. I would hate to see that happen to someone who has already suffered the loss of their prized pagoda. Better to pay the extra few dollars and keep your policy in force.
