Those $5000 (in this case Ford) dealer markups are just fine – they force their prospective customers to vote with their feet and move to buying a Tesla. Just one more nail in the coffin of dealerships – they don’t have many years left before they will be gone.
Also, if the dealer doesn’t advertise the markup, and adds it on later, that’s false advertising, like bait & switch, and there may be laws against that.
Article too long; didn’t read it all.
