If insuring for agreed value do you insure the car for what it cost you to build or what it would cost you to buy the same spec car already built.

Thats entirely up to you and will also affect your annual premium. First one, we insured for what it would cost to buy same spec already built. Second one insured for what it cost to build.

They asked me how much it cost to build, I said 10K and thats the agreed value...
