I think she was dying of breast cancer, but I'm not for sure. She bought herself a pink (or was it red) Cadillac. She died and gave the car to her best friend who I think was Whoopi, but I don't know.
The movie is "The family that preys." It stars Alfre Woodard and Kathy Bates. The movie is about two families who don't get along, but the two older women do.
Oh okay, just that there someone had an illness and Whoopi Goldberg was there, my bad. I thought it was that one.
The only movie I can think of fitting that description is A little bit of heaven
No it was an old movie thanks for trying
Could it be "A Little Bit of Heaven?
