Disabled Veteran needs Wheelchair

Hi,
I am a disabled veteran who bought a used power wheelchair. I have a TBI and severe neurological issue that keeps me in a chair for my safety. Currently we use a ramp to load my wheelchair in our car. Recently while my wife (who is also slightly disabled) was setting up ramp while parked in parking lot, I was hit by a car that backed into me. Our hope is to remove the ramp which is dangerous and allow us to just fold chair into existing vehicle. I am only 52 with 2 small children and a new grandson and want to be able to improve quality of life for time I have left. Thank you.
