Help my mom get to her chemo and radiation

I am starting this on behalf of my mom, Deb Steinbacher. My mom has the heart of a saint and would do anything for anyone. Right before Thanksgiving she was diagnosed with stage 3 anal cancer. It has spread to her lymph nodes. She is supposed to start Chemo and radiation soon. She goes the 20th of December to have her port put in. My mom isn't working, and her husband is the sole provider, and he is on disability. Her doctors are about an hour away and unfortunately her car broke down on the way down last week. The motor blew. She has gotten numerous estimates, and it will be approximately $3,500 to replace the motor. And I know there are doctors closer, but she is comfortable with them and have been seeing her from the beginning. We are asking for help to fix her car so she can make it to treatment. She deserves nothing but the best.
