Forget the tires for a moment, the 'service' on a product without an engine or many if any moving parts is more then his previous Porsche. I think that's a fair critique, what on earth requires $100 more?
It would be interesting to know but I don’t believe a breakdown was provided.
It sounded like it may have been a mileage level inspection though, similar to how BMWs turn on the “service soon” indicator on their motorcycles at arbitrary mileages just to get “checklist” items done at a dealer. Sometimes those checklists appear to be a little more than “Spent 10 minutes looking over bike, all seems well, connected computer and cleared service interval indicator, $175 please.”
If there was actually stuff inspected based on interval (like how on a ice car something like the timing belt is a inspection interval item that is not inexpensive to have done on some cars), in that case it’s not really a fair one-to-one comparison to his Boxster in the end as there would have been labour involved in that process on the EV.
Until there’s an itemized list of what was actually done for that $800 were all guessing. Clearly *something* was done, but was it arguably unnecessary stuff? Did they charge him the $800 just to plug in the computer and check things out, or did they actually remove things and inspect stuff? Who knows. Does his other Porsche also need that same level of service as well at points in its mileage, ie my timing belt example, while the EV doesn’t at that point?
