I got my iX40 in December, my first full EV. Interesting 2+ months of driving.
I used to drive a Mercedes GLE (diesel) and my wife has a MB GLC hybrid, so charging etc. I am used to.
Had 3 options Audi e-tron, MB eqc and iX. MB was too small for my needs, Audi dealer was not really interested to sell a car. BMW dealer was great and I got to test drive the car the same day.
So far I am using free charging at my office. One choice for home is ENNAKKOTARJOUS Wolttinen XL Wallbox 11KW APP-ohjauksella sähköauton latausasema (sorry in finnish but 11 kW type 2 charging station, application to control, manual load balancing).
So far hard to tell, many differences, many obvious shortfalls compared ot Mercedes but some things also nicer. Need more experience to fully understand which I like better,
