S launched in 2012.

X launched in 2016.

Both launched with slow rollouts.

Meanwhile, the average car in use today is 13 years old and getting older. (I currently drive a 22 year old car)

It definitely turns me off buying a used model S to know it's being discontinued. And if I extrapolate that to the 3/Y, a new purchase.

Given my desire for a midsize family sedan, it makes it feel like BMW i4 or Porsche Taycan just won me over in the future.

I think of the i4 as being more of a Model 3 / BMW 3 series size car, isn't it?

The S is more in line with with 5er.

I love the way the Taycan CrossTurismo thing looks, but holy hell getting in and out of it is like getting in and out of a sports car. I expect it to be slightly compromised compared to the competition, not.. extremely compromised.
