The way things are going, the insane markups will eventually start to create a revenue pigeonhole, where dealerships can only sell to a small number of customers who are more than willing to pay 3-4-5x for something that in normal circumstances - isn't worth 3-4-5x.
So effectively, dealerships are switching their strategy of doing high volume sales (like a McDonalds; affordable) to low volume sales (like a Jeweler; expensive).
What dealerships are doing is as plain as daylight. Dealerships have probably gotten sick of selling to "everyone", when all they want is to really sell to a "select few". With this new business model, they can severely downsize their operations (layoff pretty much everyone, except for a small crew), and don't need huge inventory, while still making an absurd profit. Once the supply chain issues are resolved - you can be assured they will NEVER go back to wanting to do high-volume sales again. It's not worth it to them.
The side effect of this, should this be allowed to continue, is that we will have a natural socio-economic divide as to who can have new cars............and who can't, aka - who is willing to pay 3-4-5x markup for something, and who refuse.
This is why dealerships need to be regulated heavily, punished by manufacturers, or the entire industry needs to go away entirely.
The entire dealership model is knee deep in price gouging, and they're left unchecked.
