I'm really interested in getting a used Leaf, but I need to be able to transport my elderly mother in it. She had a compact Saturn station wagon but could no longer use it because the seats are too low to the ground, and that is something I fear may be an issue with a Leaf. Could someone kindly take the time to measure the distance from the ground to the surface of the front passenger seat? Thank you. I'm mainly looking for a 2014 or 15 S model.
