Tiff it really is a moot point.

The car is YOURS, the grandmother CANNOT HOLD IT FOR RANSOM.

I dont give a RATS ASS WHO SHE GAVE IT TO.

It would be like me loaning you my car, and then you saying its now yours.

As long as you signed NOTHING with the grandma, go to the grandmas house, call the cops, and say the car was stolen.

with any luck they will arrest HER.

I would say"i let a friend borrow my car and now she refuses to give it back to me".

She will HAVE TO GIVE UP THE LOCATION of the car to the cops.

CHA CHING ill be here all week
