Actually you would just have to file a theft report with the local police and the car would not even enter Romania without the driver likely arrested and the car confiscated, as there is a real time db of cars reported stolen that is shared among the EU members and more.

You would probably have to worry much more about the car being torn apart and sold for pieces or leaving Europe through Rotterdam.
