Enjoy your Y!
I have a 2017 Model S, bought my wife a new Y in December. (white on white and man does she LOVE the white interior)
Ride quality in the S (air suspension and even with 21" wheels) better than Y with the 20" wheels.
But overall handling/steering feel? Goes to the Y. Tight turning ratio, better road feedback feel, brakes are firmer. Its a winner.
Nice! That doesn’t surprise me at all given a) the air suspension in Model S and b) the smaller size and lighter weight of the Model Y. As someone who has owned many European sports cars, I feel more at home in the Model Y than the Model S though I do love the form and function of the Model S.
