When dealers negotiate prices on cars they have lots of moving parts - back end rebates, volume rebates, finance incentives, holdbacks, etc. This is well accepted as the way the legacy auto industry conducts business.
With Tesla they sell everything direct to the consumer, so they can’t blame their dealer network for the price fluctuations. To make matters worse, the price changes have been done in a very public arena for all of us to watch. Prices dropped in early January because the reduction in federal tax credits caused demand to soften.
Then Elon decided to close all of the stores and reduce prices to reflect the reduced overhead. Then he changed his mind and decided not to close all the stores, so he raised prices to adjust again. If all of this wasn’t so visible to us we probably wouldn’t give it much thought. But because Elon keeps tweeting his decisions rather than keeping them quiet, it causes a lot of noise within the community. It’s not necessarily a bad thing for prices to adjust from time to time, but I don’t think I’d be so vocal about the behind the scenes stuff until I thought it through a little more carefully.
