have insurance for with your company.

Another way said, if you have and "agreed upon value" with your company, say for $10,000, then her company is obligated to pay up to $10,000 in repairs of in total salvage.

If you do not have agreed upon value, then you need to provide documentation what other cars like yours are selling for. This will establish the "totaled" value.

They should perform repairs up to the "totaled" value.
