I'm looking to find out if I could fit a wheelchair in the rear cargo area without putting the back seats down.
Take a wheelchair to a Ford dealership and try it out.
I don't, but the Physicians Assistant who works for me does. I'm pretty sure he hauled around a wheel chair for his mother. I'm off this week but I'm sure I'll talk to him (He's fresh out of school and has tons of questions!) so I'll ask him when I speak with him.
On a side note, I have a patient who drives a little bitty Subaru Impreza and I know for fact that she hauls her husbands wheelchair in the back seat portion of their car. I've seen them put it in it! Thusly, I would assume that you could fit a standard wheelchair in just about anything.
