Just a point on easy access for Glos Guy. My needs change fairly regularly so I always search for something with very easy access whatever I feel like. One thing I have noticed on my wife’s car and on a Citroen c5 aircross, she has a Peugeot 3008, is that the french cars have electric seats with an extra big range of movement. So much so that I regularly have to warn rear seat passengers if I am moving back. It means access is very easy as they adjust widely up and down and reclining as well as going really far back. The other thing about the Citroen is that the front doors are ‘cut’ out at the bottom, towards the front, so that you get a much wider opening door than is conventional. They open wide as well. The cutout allows your feet even extra space. With wide, fairly flat seats movement in and out is easier too than with bucket, sports seats.
I did inquire in the past, with other cars, about rejigging the seat connections to allow them to go farther back. There are firms that will do that if your wife needs a seat to be more adjustable.
