If it's a total, you will get what the insurance company considers the cars worth.
You can kick and scream all you want, you might get an additional $200. You say yourself it's an older car.
All used cars are bringing more dollars these days, look up what it's worth. Ask for that. No more, no less.
It is what it is, they DON'T GIVE TWO FUCKS IN A CATS ASS ABOUT YOU, OR THE CAR. No matter HOW LONG you have been a customer of theirs.
They work off of algorithms, they don't deviate and if they do, it's NOT in your behalf.
If you get a lawyer involved, you will pay him everything the insurance company pays and get $0.00.
