With the COVID-19 pandemic waning and a fresh buffet of juicy incentives on offer, used car buyers are taking another look at electric vehicles. With the right research, they can find some impressive bargains among Used EVs.

The first thing to understand is that EVs don’t depreciate like gas-powered cars. Instead, their batteries decline over time and lose their ability to charge as they age. It’s a little bit like how an old phone loses its ability to turn on, though estimates for battery replacement costs vary widely, from $0 (if the vehicle is still under warranty) up to $20,000.

Some consumers will be wary of purchasing a used EV because they don’t want to run the risk of being left stranded on the side of the road. But it’s important to remember that EV batteries are designed to last a decade or more, and most come with warranties covering at least part of their life cycle.

Also, the way that EVs are driven greatly impacts their range, so you’ll need to carefully consider how many miles you’re comfortable driving each day. You can get a good sense of this by taking the car on a test drive, paying special attention to how quickly the battery drains during sustained cruising or in cold conditions. Additionally, you should check to see if the car is eligible for any federal or state tax credits that can significantly reduce purchase prices.
