be fair, the real comparison needs to be between the normal expected wear and required services. A separate comparison should be done on the design itself (door handles, motor whine, 12V batteries and like know failure points on Model S). I believe a good argument could be made from the data that Model S has better running costs. There are no oil changes and the brakes simply are not used very much. You'll still have things like brake fluid flushes, suspension wear and the like as both BeV and ICE share these elements. On the design/initial production quality items that are know high failure rate items, you really need to chalk most of that up to the new auto company and not so much the inherent costs of BeV maintenance. Or at least I do as I see these two areas as completely separate. Had the BeV been designed perfectly without any high failure prone bits, it should fare well against ICE.
