How much does the major service cost, if we remember it includes engine and the entire transmission?

What other maintenance costs can you think of?

And how much does it cost to drive 500 miles in the electric car charged at £0.08/kWh vs diesel at 50 mpg (£1.91/L) or petrol car at 35 mpg (£1.58/L)?

So, one of the reasons I asked is because the motors used in EV's also are usually embedded inside transmissions which require regular oil changes (like any gearbox) and the motor itself needs to be serviced every x years - or even be replaced. These motors house Neodymium magnets - which is a rare earth metal. Although, some designs like in the earlier Teslas used coils for both the stator and the rotor using a switched reluctance design.

Plus, you have to service the steering column, wheels, bearings, etc. Not saying these are equal to ICE costs - definitely not. I just thought even EVs had to get regular maintenance as they are fundamentally the same apart from the drivetrain itself.
