>Henry Ford did not invent cars to be fixed only at the dealer and then be thrown away after the lease/warranty expires. That is a very modern phenomena.

Henry Ford invented assembly line manufacturing. A product manufactured on an assembly line is the textbook definition of a commodity.

> Back then it took knowledge and work to keep a car on the road, to deal with inevitable roadside breakdowns long before cellphones.

I'm sorry but am I to believe you were around "back then" to know what it took to keep a car on the road "back then"?
