Legal Question in Business Law in Florida

It is hard to answer with any certainty because you did not provide details about how she has the car and what your "deal" with her was. If you gave the car to her with the promise to make all the payments, she may have an agreement to enforce. It all depends on the facts. That said -- generally speaking if the car is titled in your name, then the car is yours. If the girl friend gets in an accident, you as the owner, will be held responsible for her negligence.

No, she does not have any right to the car.

Good luck.
