Our 2017 6 seater X has been out of warranty for 6 months, I have no real concerns about longterm ownership and plan to keep it atleast till 2025, maybe longer.
We could trade it in now for a LR Model Y for zero cost but am not sure why we would do that.
The only real appeal of the Y is longer range, but we live in middle England, where 150 miles in any direction pretty much gets you to edge of the country.
Quite a few people now have the Y, and 3s are literally every where, great cars but why would we losses all the extra passenger space, powered doors, and the massive windscreen for extra range we don't use or need?
I would love to replace our X with a Plaid refresh, but cost and zero availability here in the England is a major issue.
If you have never owned a X, on paper I think the Y wins. As Elon once said the X is a Faberge egg, unnecessary, over the top, but who tries to remebers the practical/boring parts of life? I love our X for the drama and occasional it brings to something as mundane/utilitarian as carrying 6 people in the car. To this day I still wonder how on earth those rear door work at ever single school drop off, and didn't we all want to astronauts at one stage in life!!
I look at 3/Ys and think those are great practical cars, I look at our X and just help but smile, that for me is the most important bit of ownership, enjoyment/fun/emotion
