Charging an EV may be more expensive than you think...

Like I said you're naive. I remember when my 4 year old Merc SL350 was going rusty here and there so I took it to the Merc dealer to get it put right - after all Mercedes guarantee their cars against rust for 20 years. The Merc dealer got out the full terms of the "Mobilo warranty" and I realised that there were so many conditions attached that no one would ever be able to claim on it. I said this to the dealer and he said that he wasn't aware of anyone ever claiming successfully. He said the best I could hope for is a "goodwill" payment towards the repairs, but it was highly unlikely that Merc would even offer this. 

If someone takes their 8 year old BEV to the dealer after the range had gone down below whatever figure they guarantee he'll be presented with a vast list of conditions (like being serviced on time at a main dealer, never crashed - or repaired at a main dealer if it has been etc etc). And in the unlikely event that he satisfies all the requirements they'll take it away and "test" it and say the battery's OK. And you won't be able to a thing about it. These guarantees are designed to never be claimed on - they're just there to make you buy the car. 

This may apply to the basic new car guarantee but, certainly on the Mercedes Mobilo guarantee you had to have a full Mercedes service history - and many other things - in order to claim. Any battery guarantee on a BEV would have to be checked to find out what conditions apply. For example some only apply to the original owner. I suspect that this battery guarantee is one that will never be claimed on because the costs are so high. There will be a reason why the guarantee is void.

I'm not sure how accurate that is, on an anecdotal level. I know a good number of people locally who own an EV as their principle/only car (including one who regularly - pretty much fortnightly - drives his Tesla from Derbyshire to Glasgow).

I've even taken the plunge and ordered one myself (I'll have it before Xmas, all being well).

I'll take my chances, thanks.

You already did Walter. I am just pointing out the EV revolution also has its downsides. It isn't all gravy, which some people would have us believe it is. Which there are a lot people already moaning about them, as they thought they were maintenance free. I know someone who is going to buy a Tesla next year, so I just said your choice these are some of the pitfalls, but if you think this the way forward then obviously buy one as you are probably buying the best EV which has been around a while and are still probably miles ahead of the rest.
