Disable disability

So I need a car that’s not on motability as I have vans for my 2 sons who use wheelchairs and 1 fully able son who I shouldn’t be using the vans for if solely for him. Having looked for ages, I bought an X-Type yesterday that I collect on 2nd Jan. My older boy is coming on the 4 hour train ride in his chair to collect it. Just got to hope the chair fits for the return journey!! hopefully happy days ahead!!
