Re: can a shoping cart do 500 dollor damage to a 9
If the lady were pushing the cart and it contacted a car, I would think that the damage would be insignificant - along the lines of a minor scuff or at worst a minor scratch. Something like what would happen when someone opens the door of their car too far and the one next to them gets a "door ding." This is assuming that the cart was only being pushed normally and not rolling freely down a steep incline or some other unusual circumstance.
A repair bill of $500+ for that kind of damage is unreasonable. This is true for almost any car, but especially on an older car or a car with other cosmetic problems. Yes, of course you can find a body shop willing to charge $500 for work on almost any imperfection, but it is a question of what is really reasonable. If the owner of the car were paying for the repair himself, he would clearly not pay that much to repair a minor scuff unless it were a show car.
In this case I don't think the lady has any legal or moral responsibility to pay anything at all unless or until the car's owner decides to pursue it in court and get a judgement.
The basis of my opinion is that every car is subject to minor scuffs as a part of normal wear and tear and you can't expect your car to remain in perfect condition in public parking lots. Furthermore, if the car were already damaged, then the additional scuff was completely inconsequential and any reasonable person would disregard it or at most put some touch-up paint on it and forget about it.
Therefore I believe your friend has been scammed. And unfortunately it is all too common that the elderly get scammed. Encourage her to not be intimidated and to hold her ground. Let the courts work it out if the two parties cannot come to a reasonable agreement. It may be too late to stop the check, but she should try. If the check has cleared, then the situation is probably a lost cause, but she could sue the other person if she wanted to. That's a lot of hassle and she still may not get paid even if the decision is in her favor, so after checking with the bank, I would just chalk it up to an expensive lesson. Encourage her to talk to you the next time someone is asking her for money and she isn't sure what to do.
On the other hand, if the lady were clearly negligent or acting maliciously, and the damage were significant, then maybe I am wrong, but it is hard to imagine how this could be true given your description of the events. I mean, did she push the cart off of the top of a parking deck for it to fall on the van below? In that case, yes she should pay for the repairs. I don't think that is what happened, though.
