There are pros and cons to this and pros and cons to Tesla's approach.That’s not entirely true. Other manufacturers sold through dealer networks don’t have transparency like Tesla for their pricing. Take an example for Audi, at a time e-tron had a huge factory trunk money incentive for dealers to move units. Likewise for typical dealers. Consumers just may never know that until u really shop for it.
A manufacturer maintaining stable MSRP then doing "temporary" or discretionary discounts at the dealership level probably serves to keep vehicle values more stable, because much of this stuff is determined based on MSRP. When you start flipping around MSRP, it feels more permanent and the added visibility of this could and likely will ripple through and have implications that don't seem obvious. It's really good when values go up, but it might be equally bad on the way down.
