For example, if it costs $3,000 to replace a battery in a 10 year old Leaf, that Leaf will still be worth more money because people will know they can replace the battery at a reasonable cost and keep driving it for many years.
A 10 year old Leaf is still going to be a 10 year old car, with all the dents, dings, stains, worn upholstery, and cracked dashboard of any other car. Some things on it will stop working that aren't worth fixing. It will look sad sitting next to a new one. As long as it runs there will still be a buyer for it, but it won't be a person with a lot of money to spend, people with money will be the ones buying the new ones. Assuming the new ones have greater range and other new features, I'm betting a EVs will decline in desirability even more than gas cars. Time will tell.
