I tend to agree with a lot of what has been said – if you regularly do long journeys towards the end of your range and you live in the north of the UK possibly worth it – but I think as a generalisation the speed you can charge at when out and about is more important – my Elroq is 175 and is noticeably quicker and useful than the Kona I had previously – pre conditioning a car before a long journey for hot or cold conditions allows for low fan and a/c off – a/c saps power just about more than anything else – so heated seats is also worth considering.
It is a different way of thinking with an EV, but I have never regretted moving away from petrol !!
