No one talks about the used car market for EVs. The battery is by far the most expensive part and the most volnurable to fail. So much so that buying a used EV is a much riskier bet.
Diesel engines are not getting cheaper/better by a similar rate. Worse, investments in that are at this point being shelved in favor of EV investments. Diesels right now are about as good as they will ever be.
Also there could be a used EVs marketplace where the battery can be serviced or even rented out (making it less riskier)
Unfortunately, that's in the ballpark for a used LEAF.
