I usually just pop into a dealership and have a sit in their display models. Any that pass the comfy, and ease of ingress and egress is added to a shortlist for test drive at a later date.
We all have individual requirements and its a personal issue if the car is for you or not.
Just persevere, go try cars when you feel up to it. It takes ages to get something that fits your needs.
Best of luck, its not as easy as you think…lol.
