A used EV for around £15k makes an excellent purchase as a city runaround, especially if you already have a home charge point. While used EV values are being hit hard at the moment (manufacturers are flooding the market with EVs in order to meet zero-emission targets), we'd expect them to become more stable over the next few years as more people look to trade their current cars in for an EV. Of course, you'll also be saving money in running costs - not just in fuel, but the long-term reliability of an EV should be better than an equivalent petrol or diesel car, while servicing costs will be lower.
