Maintenance items like replacing the two-piece rotors and their matching pads is going to absolutely blow some people away price wise. Especially now that we know from Tesla that the Model 3s people are buying are the most expensive vehicles several people have owned. Performance parts are vastly more expensive than normal consumer parts, especially for low volume vehicles like Teslas. For rotors alone, I'm expecting something in the neighborhood of $1200-1600 for a set of four. For pads, I'd expect somewhere in the $250 range for a set on the front and $150-200 for a set on the rear. I'd find those prices pretty reasonable, and they'd be relatively in-line with performance parts I've purchased for another vehicle. Brembo doesn't make cheap equipment.
Replacing tires is around $400 each for the OEM tire directly from Tesla. You can find them cheaper from Tire Rack or your local shop, no doubt, but that's the going Tesla price. Buying the whole 20" wheel and tire package is $4000, so that probably means wheels are around $600 each if you need to replace them. Again, you can go aftermarket with someone like TSportline, and those are $1760 for a set of four without TPMS.
The rest of the vehicle except or the suspension is the same, so things like coolant and lubricant flushes will be the same for everyone. Though I think a lot of people are going to be surprised at the cost of maintenance from Tesla, especially at their hourly shop rate of $175/hr if I remember correctly.
Basically, this isn't your standard Toyota or Honda maintenance. And if someone went from an economy car to a P3D expecting to save on maintenance, they're going to be pretty surprised in two years when their first maintenance is due.
