That's not easy, Leia. Our attorney's told us to work out what we could with the household division. They told us we would have to go to "arbitration" if we didn't.
One thing I learned to do is mention to my lawyer any correspondence with him and this helps my conscience and also he'll take it more seriously.
I get what you wrote and think it's good. I've had to do some similar things to get him to take me seriously.
He, too, and she, took some of my stuff and I know I will never see it again or someday will replace. It's small stuff I accumulated but would have liked-cd's or books and stuff. If I came down hard or included lawyers in discussions I have worked it out better.
FWIW, I've had to tell X that I won't sign any papers until he does x, y, z and it lit a fire under him better then just anything else.
Hope you'll get your car back. One of my big things that I just figured out how to save is my baby grand piano that's coming very soon.
