Can anyone point me in the right direction to find financial assistance for buying a handicap van?

Answer 1

Please disregard the first answer. It IS SPAM & has been reported.

Ford Motor Credit & Ford Motor Company have programs called Mobility Motoring for financial assistance with handicap vehicles.
You will find that information at Fords website:

I hope this helps.
