Final answer:
The provided references do not specify the make and model of the car Pam's mother drives. However, they mention historical vehicles like a Paige Detroit and a 1980 Chevy Malibu as examples of cars owned by women in the past.
Step-by-step explanation:
The car that Pam's mother drives is not directly specified in the provided reference information. However, the reference materials do mention two historical vehicles: Grace, a secretary in Vancouver, drove a Paige Detroit, recognized as one of the first women in the city to own a car.
Additionally, in the 1990s, Michelle Knapp of Peekskill, New York, purchased her very first car from her grandmother, which was a 1980 Chevy Malibu.
These examples could provide context on historical cars owned by women, but they do not directly answer the question about the specific make and model of Pam's mother's car.
