It sounds like you bought it used? While I'm unsure of a Tesla's longevity, it looks like you could buy a used Tesla for $35k these days. Which is cheaper than your $15k + $42k. No gas -- but I'm not sure how much it would cost per kilowatt hour. Now if you were to get a Tesla $35k and install a solar roof for $10k then you're looking at $45k and a renewable energy system, taking power out of the oil companies' hands and actually cheaper than the $57k... and that would be "free" power indefinitely -- way cheaper than the fact that you will have to continue to put oil and gas in your car.
Speaking of which, did you factor in the oil change costs? Assuming $30 an oil change, you're looking at $12k in oil changes. That's now $69k for your Camry.
Plus, the Tesla looks cooler and has faster acceleration than your Camry.
I don't think i've listed a used tesla for $35k on my niche site BUT there was an offer from a wholesaler / dealer at $35K to a seller. Have a look, I am listing private sale and dealer side : https://onlyusedtesla.com/ its my side hustle.
I'm curious, though, about the listings with regards to mileage. As has been said many times, electric cars don't wear out in the same way as ICE based cars. For an ICE, mileage is a rough approximation of how dependable the car will be. But the thing I would be concerned about when buying a used Tesla is the battery health. I would love to see a number for each car with how many miles of range the computer shows when the battery is at 100% charge, in miles and as a percentage of the initial rating from Tesla. Mileage doesn't really cover it; you can have one battery at 80% capacity because it was frequently used in Ludicrous mode, deeply discharged on long trips, and often supercharged back up to full, while another was gently discharged some few percent a day for a commute and slowly trickle charged overnight.
And the biggest differentiator, to me, of a sales site is the quality of their parametric search and database. You have a small enough inventory right now that I can manually scroll through all your listings and pick out the ones I am considering, drop the top 6 in a spreadsheet and compare them - but this should be done automatically on the site.
For some examples of parametric searches, Digikey is amazing. If you haven't from them, go check this out: https://www.digikey.com/products/en/capacitors/ceramic-capac... (understand that to an EE, each of those categories makes sense and perhaps 1/3 are relevant to their purchase decision). Now imagine trying to do this if all their parts were on Craigslist. Newegg probably is among the best in their business, when you weigh in availability and customer service, but there are too many cases where I have to select both "Yes", "1", and a few numbers greater than one to identify a value. Amazon is terrible, because you have to select a category, and the data is all provided by the seller and barely normalized. For normalization, at this point you can just manually update the database so they all filter correctly. At scale, you could get a photo of the car's VIN number and look up all the specs, with the user just entering mileage...or heck, it's Tesla, they know how many miles are on each car and what the battery health is.
Also, for the comparison, a visual is nice. Here's an example bubble chart I did when looking for a Craigslist winter beater: http://i.imgur.com/AjHRHOA.jpg Mileage (or battery health?) on one axis, and cost on the other, bubble size and color can indicate age or model.
Dang! Thank you for the feedback.
Battery health! ok let me see how i can solve this.

email me, its in the site footer. I am working on updates over the weekend and just signed a dealer to list their used tesla inventory.
You could go longer if you did periodic oil analysis plus put on a new filter (and top up the remainder) between changes. Could probably double the figure to 10k, depending on engine age.
