A by the way info if you get financing:
The NOC issued upon ending of finance tenure becomes essential permanent part of the file. Original file which was in possession of the bank has bank stamp. Registration Authority does not transfer vehicle without NOC to confirm the borrowed amount has been settled and stamps can be treated as cancelled due to issued NOC.
Often owners misplace the NOC thinking it's not required anymore and face trouble when car is sold. New owner is asked to bring NOC along for transfer as a part of the original file.
Telling this only so you may have this in the back of your mind after many years when you sell your car. I recently bought a used finance cleared car and the owner had complete file while he misplaced NOC which again had to be issued by the bank after filing an application by him which took some time to get re-issued.
