I just don't think electric cars make financial sense at all right now. All those car manufacturers saying they won't be making ICE cars within < 5 years anymore must know something I don't, but I don't see who's going to be paying that premium in the low/middle end.
But yeah, I'm thinking more about the cars like the MG ZS EV, which I actually put a deposit down on last year(and cancelled due to coronavirus and working from home, but I test drove it and was 100% willing to buy it) - at £25k it was very affordable for a full EV, with loads of space inside.
And then remember that all manufacturers always start with the most expensive models first because that's where the money is, but more and more cars are arriving form various manufacturers. ID.3 from Volkswagen is already approaching affordable prices in lower specs, but there is the ID.2 coming. And if I were to buy a second car as a runaround now, I'd happily buy a £12k second hand e-Up, it's more than enough for driving around and will cost nearly nothing to use.
Does it? What example do you have in mind? Because the only one I can think of is perhaps the E-Tron compared to the Audi Q5, and I'd argue that to reach the "half" mark you'd get a Q5 that has barely any options fitted in, while the E-Tron will come packed with tech. And then yes, there is the Tesla Model S which is absolutely not worth the money they are asking, but it's an exception not the rule. There's more and more EV vehicles where there isn't a non-EV equivalent for half the price.
