While it is true that your car might consume more oil, and some other component might need replacing, its range, assuming it has been serviced properly, should be similar to what you could get out of it new.
I do wonder if the sum of the costs of getting the ICE car back to mint condition will be the same as getting some cells replaced so you get full range again.
Well, until it dies completely (or to the point that servicing it would be more expensive to repair than replace). Then it's range abruptly drops to 0. We won't know for sure until we have more older EVs, but it may well be that EVs last much longer than that at 70-80% range. Which, especially if starting ranges increase, may be a very useful amount of range.
So old EVs can be just like old gas cars - used around town rather than for long road trips.
The car before that was a 1998 Mercedes diesel with 225K+ miles on it that retired only because of body rust not mechanicals.
It helps that I did all the maintenance, so I knew how reliable they were.
Cars are insanely reliable and people get irrationally fearful when a car turns 100K and then again at 200K.
What I said was what I think most people do. Not what is possible.
But I think most people who daily drive 175K mile cars would rely on them for a road trip without much consternation.
I know people that have literally never changed their oil.
One plus for electric cars though, fewer side effects for that kind of thing I guess?
