alt Hacker NewsTesla is a special case because they manipulate their pricing on a monthly, sometimes daily basis, and in the past they've changed the price quite significantly. In the US, the tax credits also really screw with the market dynamics. Lots of people think the car depreciates really quickly because they don't realize the original buyer didn't pay MSRP. I paid $20K under MSRP for my Lightning and in the just over a year I've owned it, the value has dropped about 7-8K. Pretty normal for the first year of a new vehicle.
Most other car prices are "manipulated" on a minute-by-minute basis, insofar as pricing is different for each customer, based on their their willingness to go hard in negotiation, manufacturer incentives, demand levels, stock levels, finance packages, and the current mood of the dealership principal.
The difference with Tesla is that their current "best price" is published out in the open.
