Wheelchair Accessible Vehicle

My name is Haileigh Chouinard recently I was told that my current car is in need of more repairs than I can handle and truth be told even if I fix it, it will never be able to accommodate the many trips to Boston, Dartmouth, and Concord we need to make to make sure my son Elias gets the care he needs. As many of you know Elias has Cerebral Palsy, with that comes limited mobility, many doctors appointments and large clunky equipment. Unfortunaly due to lack of transportation for these things his wheelchair is oftentimes left at home and his gate trainer at school. So we're asking, please, for any help at all in this endeavor. It would be great to be able to get to the appointments we need to get to and also be able to bring all the things we need to go along. Literally any help would be so so significantly amazing to us.
