For example, rear and side window motors tend to fail first because the mechanical components are used the least, become more full of dust, the rubber tracks harden, motors work harder and burn out.
The garage will help a lot but when a vehicle is on the road for 10-20yr issues specific to it's service that can't easily be foreseen or simulated in tested pop up.
Even if that's true the comparison to the maintenance and fuel coats of other similarly driven luxury vehicles is still valid.
They used subsidized electricity costs through Tesla charging network at 0$ cost.
That would be like saying MB giving 0$ gas if u fill up at their designated gas stations.
Tesla still comes out on top, but I have never heard of that lengthy repairs for MB. General maintenance a few hours, big issues a few days max.
U can take it to any MB dealership or authorized repair shop, or local shop. Courtesy pickup, drop off and or loaner vehicle. Don't even need special status.
There are costs to new general consumer for fuel on Tesla network, no unlimited free charging
It's component deterioration from age that really gets you on a luxury car. Seat motors fail, wiring harnesses deteriorate, etc.
It's also worth mentioning that they didn't crash one. With enough road hours eventually it will happen. The vehicles that can be serviced by a normal shop will be cheaper to repair.
The lack of downtime is very impressive but if it's really that much cheaper than running a fleet of town cars then why do they need to twist the numbers?
