You can't write a balanced article on car dealerships without researching why these laws were enacted in the first place. So many people here just assume "oh, it's because of greed" - but perhaps you should spend a short time first of all investigating why these laws were created and the problems they were trying to solve.
Likewise, you can't write a convincing article about removing these laws if you don't speak of the reasons why the laws were created. You need to show why these reasons are no longer good.
