Years back my husband was in an accident and his vehicle was totalled. The insurance company tried to lowball our payout so I countered with multiple comparable listings of similar cars listed online and they came up to that amount. The key is to provide proof of the replacement value required to make you whole. (We had a comprehensive policy, not just collision, and my husband was not the at fault driver.) My recommendation would be to find comparable listings online that show the dealer premiums to provide to the insurance company.
