I dont have mine yet. its a VW ID3 Tour Pro S 77KWH. my plan is to leave it in sport mode and probably charge up to 80% twice a week. for the pottering around town and what not ill prob stick it into B mode. i have no smart charger or cheap tariff right now but i have still calculated that even achieving an average of 3 miles per kwh i still lower my fuel bill by 55% a month based on the current petrol price at £1.42 and achieving 44mpg in my Honda Civic 1.5 sport plus manual.
