I strongly prefer the car selling strategy in the rest of the world (ordering it to spec, waiting for delivery) but Americans see cars differently than the rest of the world. It's like a white good (appliance)- when you go to the hardware store and buy a fridge, it's expected to be in stock and inventory. Similarly, Americans see cars like appliances and expect their choice to be ready for immediate delivery upon selection.
If/when I can relocate overseas, I'll do it.
