Get mama moving

My family and I are desperate for a new used car. Last year the vehicle we had died on us, and we haven't been able to raise the money to get a new one. Everytime I think I can start saving, another bill comes up. My husand is currently away from the family, so I'm a single mom at the moment, with no way to get to the grocery store, get my daughter to her appointments, and am struggling for rides to work. I'm not looking for something fancy, just something that will get me down the road. Any help at all would be greatly appreciated
