I have a friend with an MG4 and it's great value. The interior is spartan (seems to be the primary way electric cars save money!) but it's not that much more expensive than an equivalent petrol car - definitely cheaper when you factor fuel costs.

The UK government recently pushed back banning ICE car sales by 5 years, but I checked the adoption curves in Scandinavia (who are a few years ahead of most of the world) and basically it doesn't matter because by 2030 (the original target) almost all car sales in the UK will be electric anyway, irrespective of a ban.
