I totally agree with Mike, the more you do their job for them the better your result will be. Back when I did the consulting job for State Farm, I realized that claim adjusters are over worked and under paid. They just want to clear each claim off their desk as quickly and easily as possible. Most of them know nothing about cars in general, especially not oddball ones. If you present them with enough paperwork outlining all of the parts, rework, condition, benefits of YOUR cars right up front (before they have time to start doing it themselves), the more likely they will just use whatever you give them and be done with it. Essentially you are selling it to them. So like Mike said, make it all look complete and professional (even if it isn't). And don't be afraid to upsell it. That way they can pass it along with their paperwork when the check stub goes to their boss's office. By the way, none of this has anything to do with your agent. Insurance agents are just the salesperson, they have zero relation to the claims department or any other function in the company. So regardless of how nice your agent is, he can't help you here. Claim adjusters sit in cubicles in big office buildings and deal with idiots and paperwork all day long. Their job is to save the company money, so your battle is with them.
