The other factor to consider is ease of drivability. It will be easier for her to maneuver the Toyota, and probably better on blind spots. Being a new driver, this will likely matter more than it would to a seasoned one. You also don't want it breaking down on her, and a '11 Toyota is less likely to. Some people may dissagree, but I think there is a reverse logic to getting a car that handles better in snow. People can become too comfortable, and then actually push their car more when it is good in snow. Depending on where you live, you might actually want there to be a reasonable amount of danger so that she is alert and drives at safe speeds. If she has the false sense of safety that her car "can handle itself in the snow," then she may not feel the need to be as alert, which will actually just make her a worse driver in the snow.
For all these reasons, I would go with the Toyota.
