@abirnale: Exactly same thoughts on almost all points. You instigated me to open up my heart a bit for my partner too.
My partner (2015 W10 M) has clocked almost 1,30,000 KMs and still runs like new. Fill fuel, check air/ lubes, and you are ready for a highway trip.
I may be wrong but I have the feeling that, as the car is aging, it's performance is slowly increasing. The smoothness and mileage has increased considerably after 1 lac mark or may be we have adapted to each other so much that we know the sweet spots where to play around for a better performance

.
Whenever the thought of upgrading comes, my heart aches to think that I will have to part with my partner.
Low maintenance cost, excellent fuel economy, the apt size, abundance of space for my family of 3, that high stance from the cockpit, that flat bed experience where I have slept many nights in petrol bunks and my daughter occasionally stretching up her legs on long journeys till the middle row with the 40 split bent down, excellent service support from my local ASS, everything goes "for" the car to keep her till the NGT rule in Delhi NCR compels me to marry her off to someone competent.
I plan to wait till the new XUV 500 launches + 1 year or the new Thar in 2022 for an upgrade.
I have been troubled only once in the entire ownership till date, that too near my home due to the famous slave cylinder failure but even then I could drive her home. So haven't been literally ditched by her on the roads.
I was once discussing with the service center guys about my initial intention of getting the new Thar, and they themselves prohibited me to sell my partner off, as, as per them I have maintained her so well, and she reciprocates so similarly and she still behaves like a newly wed

. Hearing all this, my love for my partner has doubled instantly.
Partner gets her personal little pampering every weekend. Even after a complete detailing by someone, I still have to do my own bit to my liking, like wiping of the water marks dropping from the ORVMs - from rear number plate - door handles etc, interior dash buff to a matt finish, to clean the little specks of dust in the absolute corners of the screen and in between the switches.
The rattles in the car were marred down to almost nil by inserting double sided tapes/ cello tapes in between the panels and sometimes opening up a panel, taping it etc. Almost all joints/ panel gaps are attended similarly. Jack, spanners and other tools are wrapped in cloth with individual wraps in between and secured and padded properly for no sound. All seat belts are properly secured for no noise while on the roads.
Last few months have really compensated for all the total locked down months and I have totally enjoyed every bit of it.
Nov' 2020; did a solo Delhi Assam round trip covering more than 5000 KMs. Crossed Brahmaputra on a ferry with her (It's quite an experience to drive in and drive out of the ferry to the banks). Traveled on very very bad roads. Never had a trouble with the car. Due to some very bad patches of roads, which I crossed at high speeds and on two occasions where the car flew for few feet after crossing river bridges where the roads are lower than the bridges, it gave me a heartache and I totally suspected of a suspension damage or cracks but nothing observed up on an inspection in a garage.
Dec' 2020; did a family Rajasthan trip covering more than 2000 KMs. Excellent ride on the empty good tarmac roads of the desert state.
Mar' 2020 ; did a family Jim Corbett trip. Rode on the dried river bed of Kosi river and bathed her with the little stream of cold mountain water.
It's an emotional bond which I have developed with my partner and her faithful nature to all my adventures is the sole reason of loving her so much.
Hope my next ride to be a good one.
