That is funny, but then the Dealers will do anything to charge you for crap.
I took my Tesla for its first 'service' last month, bought it new in Sept 2019.
So, 3.5 years till first services.
Only took it in to replace the 12 volt small battery under warranty.
They checked all systems, balance, rotate and align tyres and the service cost me $250.
Not bad given I drove 34,000 km over 3.5 years with a total service cost of $250.
