Whose car does the woman claim is fantastic?

The woman claims that the car is fantastic, indicating a personal connection or ownership when she refers to it within the context of the conversation. When someone asserts that something is "fantastic" in relation to a car, it often implies pride or enthusiasm about their own possession. Therefore, if the woman states that the car is fantastic, it is logical to conclude she is talking about her own car, as that would evoke a sense of personal experience and satisfaction.

In the context of the other options, if she were discussing someone else's car, the expression of enthusiasm would typically be framed differently, for instance, by acknowledging the owner. The use of "fantastic" in reference to her own car reflects personal pride, making this option the most fitting in capturing the essence of her claim.
