The agreed value of your antique or collector car is a value that both you and the insurance company underwriters can agree on.
Using photographs, receipts, repair documents, and other information, both parties come to an agreement that the car is currently worth a certain dollar amount, and should be covered for a maximum of that amount in the event the car is totaled.
The agreed value is different from the actual cash value, which is based on the age, mileage, and overall condition of the vehicle as well as other factors, including depreciation.
The reason agreed value is important for an antique or collector car is that you are the only one who really understands how much you have invested in your vehicle. It takes into consideration the amount of time and money you have spent restoring the car, as well as how much you might charge if you sell it.
Normally, insurance carriers are willing to offer you the amount of coverage you desire; however, the greater the coverage, the more expensive your premium will be.
