If a creditor gets relief from the automatic stay on a vehicle and the bankruptcy is converted from a chapter 11 to an involuntary chapter 7

That depends on what the order on the relief from stay motion says.  If it's binding upon conversion, then the creditor can sell or repossess the car.  The Trustee can try to sell it prior to those events occurring.  If it is not binding on conversion, then a new relief from stay motion would need to be filed.   Either way, until the creditor has repossessed and sold the vehicle, the rights and title to the vehicle belong to the Trustee.
