An ev will be a load of trouble at 200,000km onwards if it even gets that far, the batteries are not proven for commercial use, sales rep and taxi drivers. There are people on youtube claiming 1 million miles on a big battery tesla, but when you look into it they are on their 4th battery and multiple motor changes. Stay as ye are are go hybrid petrol or diesel. At least you can get a few quid for it if its looked after. Somebody will want a cheap runabout that will do 1400km on a fill. Your going to see the scrap yards full to the gills with 7 to 10 year old evs with snagged batteries.
