Been driving electric since 2018 and just helped my sister buy a used one last month, so figured I'd share what actually matters when you're shopping. The used EV market has gotten competitive lately, and a lot of folks are jumping in without knowing what to check. First thing: get the battery health report. Some makers will run a diagnostic for free at a dealer, or you can use a third-party app that reads the state of charge data. Don't just trust the range number on the dash, because that estimate swings based on how the last owner drove. Check the charging history too if you can. A car that spent years on a DC fast charger daily will have more battery wear than one that mostly charged at home overnight. Ask for service records the same way you would with a gas car, and look closely at whether the coolant loops or battery thermal system were ever serviced. Tires matter more than people think as well, since EVs are heavy and chew through rubber faster.
One last thing. Take your longest realistic trip into account before you buy, not just your commute. Cold weather cuts range noticeably, so if the car barely covers your weekly driving on paper, winter will make it uncomfortable. Test drive it on a highway if possible, not just around the block, and see how it handles at speed. Prices are decent right now compared to comparable gas used cars, so if you do the homework you can land a solid deal.
