That is called "agreed value" insurance, I don't know that much about it, but companies like Hagerty or others offer it, they have advertisements in collector car magazines.

An agreement is reached about the value of your car with the insurer, after I would presume an appraisal, and the car is insured for that amount.

However, therfe are restrictions with collector car insurance, with very low mileage driving requirements, usually 1,000 to 2,000 miles per year is allowed in the typical cases.

Agreed value insurance I think wouold be difficult to get for a restored car being used as an everyday driver, because the risk to the Insurance companies would be simply too high, as with zero deductible insurance (because the Insurance companies would go broke paying for every single parking lot ding to be repaired.)
