Historically, car manufacturers screwed dealerships. One of the ways was selling franchises then deciding that they could make more money selling directly to customers. Or that they needed some extra cash, so selling so many franchises that none of the dealerships could sell enough to break even.
Many of the laws about warranties were due to poor behavior of manufacturers. In the US, repair parts need to be available for at least 10 years for cars. In the past, the manufacturer could just decide that they didn't want to sell repair parts - just buy a new car.
The Great Depression reduced the number of car manufacturers by about 95%. Which brings me to a more important point. A number of laws were passed to prevent the Great Depression from happening again. Repealing several of them gave us the 2008 financial crisis. Making exceptions to the Securities Acts of the 1930s lets us all relearn the history of why those laws were passed in the first place with all the crypto scams. These laws exist for a very good reason and repealing them is only good for con artists and crooks. The rest of us get screwed.
Modern car dealerships in America are the embodiment of modern rent-seeking. Every department treats every other department as the enemy. Each department that touches an item (spare part, used car, tires, floormats, whatever) has to raise the price 30% to cover overhead and the need to be a profit center. Sears went through this exact same behavior as it crashed and burned. Jack Walsh used the same behaviors to make General Electric the darling of Wall Street.

Every sales rep that works on commission works this way. Salaried sales reps don't. Any commissioned sales rep that refuses to work this way ends up quitting very very quickly.
Disclaimer: I used to work for General Motors which used to be the largest car manufacturer and the very reason that many of the dealership & warranty laws were passed in the first place.
