Used electric vehicles (EVs) generally cost less than their gasoline counterparts due to a number of issues. The older the EV, the more the battery degrades, and batteries can cost from $5,000 to $20,000 and more. In addition, EVs are rapidly improving, making older models less desirable. Keeping an EV for the long run is generally the best way to maximize the initial investment due to the fuel cost savings. See
