That's a horrible argument to make since Musk regularly touts that Teslas keep their value the longest.

KBB has estimated that the Model 3 will retain 69.3% of its value after 36 months. As far as I can see, that is neck-and-neck with the best KBB estimates for
any vehicle - electric or otherwise. Top spot would be Toyota Tacoma at 69.4% value retention after 36 months. Although trucks dominate the Top 10 overall because the 5-year drop is less than with cars, Tesla's included (the popular trucks are in the mid to high 50s after 60 months, versus a lower, but still very respectable 48.7% estimate for Model 3).
It should be obvious to people by now that Tesla does things (everything)
iteratively. People complain that they are not selling a $35K vehicle that was promised (fair enough). Tesla talks about making the most affordable car they
can make at the moment while still needing to maintain a good profit margin to maintain viability. Tesla was never going to just produce top-spec $70K Model 3s and then one day magically start selling a $35K model. They started higher and are continuing to drive the price down. Introduced the mid-range model at $44K. Then dropped it a bit further to $42.9K. It's possible that mid-range model might get down to $40K before a standard interior, standard-range $35K base model becomes available. Maybe not, but it's certainly possible.
When you buy any vehicle - whether a Tesla or a GMC pickup...as long as you get what you were promised when you bought it...then it seems to be it was a square deal.
I bought a Model S (high spec'd 75D) in mid 2017 when glass roof, PUP, premium audio and other features were all
options. And expensive ones at that. Now those are all standard equipment and today's Model S (or even the ones for sale a month after I took delivery) is a much better value. I could have got (essentially) the software limited 100D they are selling right now and got a bigger battery and all the other equipment (that is now standard) for almost the same price as I paid for my 75D twenty months ago.
Was I "happy" that Tesla made $5000 or so of options standard equipment on cars made a few weeks after I took delivery? No! But I got what I ordered and what I paid for. The fact that they made the car essentially $5K cheaper / better value was something that they did to make it even more compelling to new buyers. Shouldn't have been surprising that they would continue to drive prices down and value up on Model 3 variations. They will continue to do sell the cheapest car where they can still make ~20% profit on.
