Special Needs Family Car

I’m a single and solo Mum of three boys all with special needs. We attend a lot of appointments and my boys attend different schools due to their disabilities. Yesterday my car blew up, I’m a survivor of DV and do not receive any additional financial support. I am blessed to have received a government house but it is not in an area with great public transport. I desperately need to purchase a cheap second hand vehicle to get us around to school and medical appointments.
