For the less mobile, the ideal car is where you can simply slide across onto the seat, without having to lower oneself onto it - at 6'0" a SUV with seat at highest position works fine for me although SWMBO at 5'3" has to climb in and jump down.Ideal car is one where you can easily lower your self onto the seat without having to bend you knees. Then swing in without having to tuck knees under chin.
