I agree! Personally, I do not think much of the Model 3's appearance, nor of the Model Y's (which I have not yet seen in person), but so what? What matters is their utility, their value to the user. You cannot see much if any of the outside when you are inside! So what the interior looks like is much more important, really -- that is what you will be experiencing as you ride and drive. But more important than that is how well it works for you, how it does its job, how it rides, drives, performs, functions.
I agree that a beautiful car can be more fun to own, because you get compliments and so on, but ultimately that isn't what I pay for....
