Mobilize the Buffalo

We have been going through hard times since my mother passed away, and we haven't once asked for help, but we're stuck between a rock and a hard place, today when my father and I went out to take him to dialysis and myself to work, our car decided to die, and not in a, you can fix me easy kind of way, nope, we need a whole new motor, instead of replacing the motor in a 13 yr old car, I would like to find dad newer vehicle but even with my paycheck coming in I cant afford to get us mobilized again I am too far behind on bills, im afraid were sinking and will not come out of this with out help or prayer.
