Check the mileage limits you can drive, if any, that are on the policy. I'm an insurance broker and write classic cars with a company called American Collectors. They limit the yearly mileage to 2500, the car can't be used for anything other than driving to auto shows or just a cruise. If you stop to pick up a gallon of milk and the car gets hit they'll say you were using it for errands and won't pay. But even here in Brooklyn, NY where there's some of the highest rates in the country I have a 69 Caddy convertible with an agreed value of about $18,000 insured for about $136 a year.
