No documentation for the loan of an automobile.

This is with regards to one of the old vehicle that we have (Maruti Van) which was bought in 1994. - The same was bought in the name of my maternal grandmother and the vehicle was financed through a financial institution called - Manipal Finance. - The loan has been re-payed by my father to the financial institution but the document has not been collected for the repayment of the loan. - This financial institution (Manipal Finance) has closed down since long back and my grand mother also has expired - who is the official owner of the vehicle. -

Neither can we get the documentation of the loan cleared from the financial institution nor can we get the transfer of the ownership done as my grandmother in no more. This vehicle is with us since many years in an un-used condition. We would like legally dispose this vehicle - by either selling this vehicle or scrapping this vehicle by selling it to the scrap dealer. Please suggest.
