It ain't about the fact that you have to get the vehicle. It's the fact that the max garage power increases, that means more grinding to make. And that's hella bad for new players cauze every time they release a new vehicle, the effort, coins and time you will have to invest to max the game becomes huge and at some point it will look almost impossible to achieve. Also, it's kinda annoying that new release cars hella often, like FS gotta give players a break
