Torque:
Silly question from a prospective buyer - how is the Y much of an upgrade from the '3? Is it just the extra space?
I wouldn't really class the Y as an upgrade to the 3 but rather, it's the more practical option if you have kids/dogs. For someone like myself who has neither, the Model 3 is the better option for its more nimble sedan aspects. Outside of cargo space, the only true upgrade to the Model Y RWD vs the Model 3 RWD is that the Y comes with the premium audio package whereas the 3 does not - you need to get the Performance for that.
