The typical two-post lift that's in every bay is like $3000. The various dealer service tools (several-generation-old toughbooks with a 500% markup) are also in that ballpark. Then you've got various flush and fill machines, refrigerant recovery and vacuum, etc, in the $1-2k range each. And then there's a whole menagerie of special little jigs and thingamabobs that're probably each in the $20-200 range, but which save a lot of scraped knuckles and swearing and such.
If you head to a performance tuning shop, you might find a 4-wheel chassis dyno worth about $50k or maybe more, but dealerships don't have those.
I think hesitancy by dealerships is in the long term EV’s require much less maintenance and that means their service and profits will be much less.
Their service departments are equivalent to the much higher margin soda.
