Going 100,000 miles is not the same thing as lasting "forever," which is around 250,000 miles in my opinion.
I have a 266k mile 04 4Runner, a 250k mile 04 F250, and a 188k mile 13 Chevy Volt.
'Forever' is starting to be 350k miles in crowds that don't buy new vehicles.
100,000 miles is essentially the bare minimum I'd expect from a car. I enjoy spirited driving as well (rumbly subie owner) and I'm over 100,000 miles and only had to replace wear items.
You must be very careful driver then. And the roads must be very good around you. I am pretty sure, I will need to replace something in suspension of my model Y before 60000 miles.
I assume your (probably more carefully driven) 100k did less wear than the 70k done via rental.
I earn too much to receive any incentives, so keeping an eye on the used market to buy another Tesla or two (preferably Ys, but would take a 3).
Edit: I enjoy spirited driving, and do so frequently on roads of many different quality across the eastern US and Midwest.
