When the expected higher resale value of the M3 is factored in, this analysis determines it is significantly cheaper than a Camry over only 3 years.https://www.marketwatch.com/story/this-math-shows-teslas-model-3-is-chea...
While it isn't clear this analysis fails to do this, most of these analysis fail to account for the opportunity cost of spending the extra money on a Model 3. Most Camrys sell for low 20s so including sales tax and EV incentives a mid-range model 3 is at least $15K. If one pays cash for both cars with the Camry one has $15K which can be invested. That needs to be factored into the analysis. Of course if one is financing and paying interest on the loan that also needs to be factored in. Of course no one concerned and knowledgeable about costs buys a new car and then sells it after 3 years.
I think a 3yr CD is under 3%, but lets just use 3% for ease of math. The interest earned on 15k over 36 months at 3% is $ 1,350.00.
I didn't see in the article what mileage they were using, but lets use 12,000 per year, so that equates to $ 0.0375 per mile adder to the tesla, which would still put it under the Camry per the article theory.
