Things start out as a luxury, which you pay extra for, then eventually become standard. Like Radio, Power Windows, ABS. Some things are luxury, sold as a "package", but to try and buy a car with out the package is almost impossible. Try buying a Toyota with roll up windows, no radio and manual transmission and it will take a year to get it from the factory. Special rims, heated seats, etc. Since it is easier to build products all the same, it is cheaper for the manufacturer to include them. I had a car where on the dash you could see where various buttons would be, like push button start, but being a base edition, were not included. All the wiring is there, the place for the switch is there, but not included. BMW thought they could move the upfront cost of buying heated seats to a monthly, and more importantly, the lifetime of the car, payment model. Instead of just not adding the buttons to the dash on the blah blah package that included the seats, they taunt you with "here are the buttons, but you can't use them". If they just had a car with the wiring in the seat but no buttons, and no monthly charge, I don't think people would be as mad.
