As Ron says, shop around. A member of our club, an agent, found me a $20K agreed value policy for less than $200 a year. Most of the carriers have a sort of blue book they go by and won't insure above that value. I originally wanted $25K coverage but they would only go the $20K. Practically speaking the value of old vehicles should go up over time so have your insurer check this every year or two to keep up.
