It’s worth noting how expensive adaptations are too non motability, for one car with hand controls, transfer plates and hoists it would’ve cost about £8k minimum. For the hoist, the actual loading and unloading should be okay, if you get a compact self propelled wheelchair (if you’re able to), as you can then have it in the passenger seat or in the back seats and grab it out and then transfer between them and put it in the car.
