Dealerships’ biz model is based on repairs. They sell you the car for marginally over MSRP, then they charge the mfgr for repairs while you’re under warranty and charge you exorbitantly once you’re out of it. EVs have so little maintenance and service required that this model just doesn’t work. All the new pure EV’s (Tesla, Lucid, Rivian) operate this way because they have no baggage associated with long standing dealership networks.
