I sold a car 1 month and 1/2 ago, now she complains!!??? ?

Call her once, to tell her never to call you or your work again. Let her know if she does, you will file suit against her for harment. You sold the car as-is over a month ago. Who is to say what she has done to it or how she has driven it since then. Don't worry, as she has no case against you.
