I mean there's ways. They could just not sell to dealers who are found to be selling over MSRP. It won't be easy, but having an online direct channel makes it a lot easier. Depends how committed you really are, I guess.
Price functions to clear the market. If the MSRP is too low, then you are going to find waiting lists. It is not like dealers like selling at a price that forces them to carry more inventory than they need to operate.
