Depends on your view of a decent range and what a premium car is?? I’m sure there are lots of EV drivers who are delighted with their vehicles and the money they are saving. Still if range is the be all and end all then enjoy your visits to the petrol station and your big fuel bill’s.
I actually make money as my company pay me mileage so the fuel bills are irrelevant. Anyway I’m averaging 45mpg in my BMW so I wouldn’t call them big anyway and I would much rather drive what I have then any of the EV’s on the scheme. As for range, I would require it to be at least 300 miles to be practical. As for what defines a premium car, the EV’s I would class as premium are not on the scheme and I don’t expect them to be any time soon.
