Sadly, there aren’t cars with adaptations sitting around to be loaned or hired to people. As I see it, you have two options. Either take the Rifter or, if it’s not practical for you, speak to Motability and ask if, in lieu of a hire car, they will pay for taxis whenever you need to go to hospital. I think that’s something they will do in these circumstances. Good luck. It’s a very difficult situation and I feel for you. My wife needs a hoist to get in and out of the car now. If we were without our car she’d really struggle (as would I).
