The Princess and the Cabbie (1981)

This is a real good film about a spoiled and sheltered girl who doesn't know how to communicate in a social world. One day she is driven to an apartment by a cab driver and she leaves her wallet in the car. He tries to find her and then notices that she has a problem. He is studying with language and wants to tutor her, what develops is a memorable love sequence. Bertinelli is very young and beautiful and perfect for the role, I especially loved the ending.
