Help Chris & Sandra Replace Their Car

Like so many, many people, this last year has been extremely hard for Chris and myself.  Chris has had so many medical problems, starting with a stroke last February.  We've gotten through most of the complications pretty well, but this might break us.  Our car finally died and we have no resources to replace it.  We need reliable transportation to get to Chris's many doctor appointments.  We really need a running car as soon as possible. Any help would be so greatly appreciated. 
Thank you so much, Sandra
