Ok, not the most interesting design question - but is it? Will fit child seats, pram in the trunk etc? My husband and I have reserved our Model 3 today, woo hoo! The model S and X were too expensive for us, but this is perfect. We live 5 mins from a supercharger and there is a council car park below our apartment with 4 free electric charging bays. While you don't get much in the way of financial incentives here in Sydney ($30 off registration, Thanks Mike Baird!), we love the look of the car, the technology, the fact it will keep updating like a computer, safety, etc etc, and we want to do our bit to help change the industry towards electric cars. But, by the time it's delivered, we'll probably be in the family stage of our lives, want to make sure it will work with that as well.
