Would You Aid in Repairing My Mom’s Car?

I was driving in the rain the other night and unfortunately someone ran into me turning left at a light and did a lot of damage to the car's front rim and axle. It's undriveable at the moment, and is the only transportation between my mother, my sister and I, so we have no way to get around until it's fixed. The amount I'm asking for is half of what we need to pay off the car, and we are working to acquire the other half.
