About TSLA maintenance

I have been owning Tesla cars since 2017, my experience

1: Overall maintenance cost will be absolutely lower than traditional ICE cars. My oldest model S,  which I am still driving, never had to do any maintenance in last 7 years. Only did tire change and wiper change. 

2: The Model Y we bought 2 and half yrs ago, no maintenace whatsoever so far.

3: I did hear from some of my friends that if Telsa got an accident and need to go to body shop, the repair cost would be 50% higher than other ICE cars.
