That's a fairly reasonable amount for increasing electrical capacity, laying cable, and installing chargers. You can't just put all your chargers on one circuit

That's a fairly reasonable amount for increasing electrical capacity, laying cable, and installing chargers. You can't just put all your chargers on one circuit, and running a whole dealership means having plenty of available chargers. I'd also expect some of the cost goes towards purchasing tools and equipment for working with a significant volume of EVs. I'd expect some high voltage tools are simply not needed for most ICE vehicles.
