And I saw another response you made about people from the midwest and how we're all hicks. Isn't it so! People do think that. I'm in Nebraska also and I know. It doesn't matter that I've lived in Seattle and Boise. I'm still a stupid hick! (Ha-Ha)
As to your question. I don't think divorce court or family court, wnichever it is called, would enforce the fact that it was ordered to be sold. (I don't think) If they don't, you can always take her to small claims. I've personally had to sue for things in small claims several times in my life so I feel I can speak intelligently about it. A small claims filing fee is very minimal. You just need to bring the divorce decree and title to the car with you and that should be enough for a small claims Judge to award the car back to your husband. Especially since the car is still in his name. But you would still face the same problem with enforcement of the Judges decision. BUT with a small claims decision you can do things like; garnish wages, attach bank account funds, etc.
I wish you the best of luck and again, thanks for standing up for me when I was being lambasted!
