I think she meant the seats are higher than let's say a low seated sedan like WIRA. She don't want to bend her knees. Most compact cars fit that bill. Not the car/ride height.

Well that is how i ended up buying an Almera for ferrying my parents. Gap from door to seat small enough. roof high enough. however, many complain Almera feels under powered. It is really a big car inside, not easy to find parking if you park illegally at roadsides like wet market or hospitals. Anyway Persona saves you more money.
Yup, TS is using it to ease elderly in & out of the car. So cars that the seats are position just nice without bending or hurting their muscles/joints.
