Congratulations! I know you've heard this a bunch of times already, but you will truly love your car.
When I first saw a model 3, I didn't have a chance to get close enough for a really good look, but I remember thinking, "there's no way the inside of that car is going to be big enough for our needs." Imagine my surprise when I first sat in one; it has more interior space than our 2016 Accord has/had. I haven't looked at the exact numbers, but even if they don't back that statement up, it sure feels like it has more room than the Accord.
