Ed,
Standard auto insurance is never going to cover the cost of an older, collectable insurance, except for liability. There is not even a Blue Book value on these old cars. My company, American Collector, out of Cherry Hill, NJ, has my 73 TR6 insured for $26,500.00, no deductible, and all the other attachments, like liablity, etc. That said, I had to submit a reasonable list of receipts (probably a legitimate appraisal would do) as well as a set of good photos. They also limit the mileage to 2500 miles per year, but aren't that concerned about how much you drive. No one with less than 10 years driving experience is allowed to drive the car. Total cost: $186.00 per year. I asked how they could insure the car so cheaply and they said that the average collector car owner takes better care of their car than they do of their wife.
