That ICE car had an 8 year guarantee or less when the first owner bought it too. The guarantee/warranty length isn't full lifetime. We don't know yet what the full lifetime will be in practice yet on some EVs.

You like old cars and possibly like doing the maintenance yourself, good for you. I don't.

I want to travel in comfort and safety and not have to worry one second about my car breaking down. I also don't want to spend a single second servicing my car myself. I want it to take me from A to B every single time without fail.

I had enough "fun" with cars old enough to drive when I was young and less well-off. Can't beat the excitement of a car randomly breaking down on a remote road in -20C weather. Oh and it just as randomly started working after my uncle drove for 30 minutes to rescue us. Never again.

What is their guarantee? You're comparing apples to oranges.
