Did the attorney mention why you can't go get the vehicle? It's yours (well half yours), I mean is there any legal reason? Maybe he just thinks it's not "fair". Now it's even costing you money. Unless he gave you a legal reason, I would be looking for a new lawyer (if financially feasible).
That aside, don't feel bad about what you said, maybe it was harsh but it was also the truth. They are ugly truths, I understand your anger.
