Family with special needs children

My wife and I are parents to three special needs children we purchased a new car March last year and have had nothing but problems with it. Multiple engine replacements a transmission replacement and it’s kept us in a real struggle to keep up to date with our rent and other bills as we’re both low income on carers payments. Any money raised will go towards bills, food and fuel as we are currently using anywhere from 250-350$ in fuel every two weeks as all three children are at different schools due to their age and special needs. Plus 20+ allied health appointments in a month.

I appreciate any consideration. Everything helps.
