Medically suitable car for our family

I'm a single mother to, 3 wonderful children our youngest child has, cerebral palsy and vision problems along with other medical needs I nó longer have a car and we desperately are in need of one to be able to get him to medical appointments and therapies as we live hours away from most of them and he does not travel well on public transport as extra noise and unfamiliar things terrify him, we are saving to get a medical modified car to suit his needs that will fit his equipment now and as he gets older and they change, I can't afford it on my own as I am struggling as a single parent with no family to help us out, once we reach our goal any extra money I will give between the charities that have been amazing to him since he bacame sick and has helped not only us but many other families in similar situations, I want to thank everyone in advance for any help you can provide us and your support will not go unnoticed as this will be such a life changing help for our family,

I will update again soon, thank you for talking time to read and help, means the world to us
