I also own a Tesla. Over the 6 years I have owned it my automotive costs have decreased by some 80% compared to the ICE vehicles I owned prior. Significantly, the “no oil changes/no weekly fill up” costs immediately saved me around $2800/year. Maintenance costs have dropped to next to nothing, primarily being around tires and windshield wiper fluid.
There’s also no risk of getting a catalytic converter stolen.
What are your expenses that are so dramatically above the norm?
