What alternatives should I consider to a used MG ZS EV hatchback?
If you're looking specifically for an electric SUV, try a Hyundai Kona Electric. It is a fair bit more pricey, but then it does go an awful lot farther on a charge and is nicer to drive.
For those just looking for a practical electric car, there is a choice between popular options such as the Renault Zoe and Nissan Leaf. The latter is the more refined option and the 40kW version offers a similar range to the ZS EV. The Zoe, on the other hand, has had numerous updates over its life, so you'll need a later version for better range, plus you'll need to make sure you've gotten one with rapid charging capabilities because not all examples have it.
