I&#x27;m a big fan of the economy&#x2F;value of used cars, but I don&#x27;t think that we&#x27;ll be seeing 15 year old used lithium-batteried EVs being viable. The capacity losses from time on the Li batteries are just too severe over that timeframe, and dumping oil into a 15-year old IC engine is worthwhile. Renewing the battery pack on a 10-15 year old EV isn&#x27;t worthwhile (or is worthwhile, but puts a floor on the used car price).<p>My household has a 190K mile, 2005 Honda CR-V and a 6K mile 2015 LEAF. That Honda is likely to be viable beyond when the LEAF is viable. (Assuming no accidents, rust will eventually get the Honda and battery capacity will get the LEAF.)
