Go to an insurance company that insures classic and specialty vehicles, like Hagerty in traverse city Mich, or a similar company. They allow you to do a stated value policy (within reason), as to what you believe the car to be worth, amount invested, plus rarity apprieciation, etc. They are also affordable as they know classic car owners are careful with their cars and watch out for them, as well as not drive them much. I had a 55 chevy I insured for $25,000 full coverage for $650 a year.
