For anyone reading this and still interested in the original topic, please get a 3. The last thing the world needs is another SUV. I know people that bought an SUV just so they can see over the SUVs. They are more expensive, slower, less efficient and handle worse. Additionally, you become part of the problem. For me a big part of buying a Tesla is to be part of the solution. Environmentally and from a road user point of view. I've owned sedans all my life and a couple of 4x4s. There is no chance I'd ever buy a compromised car like an SUV, my 4x4s were for off road stuff when I lived in the bush. I used to travel 600km trips regularly, at night and the ability to dodge things was very useful. You just can't do that in an SUV (though EVs are generally better due to their weight distribution). I do like the X Wing doors on the X though. Not enough to buy one, I'd have an S in a heartbeat to replace my wagon, but not an X.
I haven't got the 3 yet, but the boot is more than adequate (if a little oddly shaped) and coming from a Commodore based vehicle, I do like a big boot. As for SUV space, save your money and rent something for the 1 time a year you need more space.
Of course everyone's opinions are different. That's mine.
