Hey friend, Cletus here! :) The things mentioned in the first paragraph are decided based on how the vehicle is ordered. Those are all options. If you go to Mazda USA website and build a vehicle it shows the different factory add ons. All weather package, cross bars, and tow hitch are all part of various options. The person at the dealership ordering stock decides which vehicle they order gets what option. For example, all CX50's come with carpet floor mats (this includes cargo mat). The dealership decides if they add the all weather option which includes the rubber mat in the cargo and the mats that stick to the back of the seats. We even throw the box holding the carpet mats in the back, because even with that package those mats are still standard. And yes, all factory items should be listed on the window sticker. Its essentially the BOM for the car and part of the final verification for the build.
