if you have the title, take it with you to retrieve the car? No?

So you'll have to go to court and prove that it was fraud'd away from you??

Makes no sense, by that time everything of value would probably be stripped off of the car. You gave the thief too much notice, they're probably steps ahead of you scrambling now.

Did you guys not report it stolen and wasn't the title in your dad's name up until you reported it Stolen? How could he have provided sufficient proof to the cop? I say you raise hell until they take action. Or take action yourself and get the car back. If he had the documentation to "prove" it was his, you guys surely have the real deal to back it up should he try to call the cops on you.
