buy a wheelchair capable vehicle

I'm Jeremy, and I'm a disabled veteran. I served 17yrs in the Army and was medically retired in 2016. Recently I was in an accident and am now a paraplegic from the waist down. I have 4 separate fusions in my spine now and will likely never walk again. I need to get a wheelchair-converted vehicle so that I can maintain some level independence and mobility. These vehicles are not cheap and I simply can't afford to purchase one outright. I don't usually ask for financial help, but I truly need it now. Any help will be greatly appreciated! thank you
