They're using the same idealogy of overpricing stuff and listing it in Amazon, so they have the first exposure, even if most expensive, it's most convinient.
I, value 50% of the car's price and don't mind spending 3-6 hours to save $10,000~ but many people, simply have an old car, the mechanic says it needs a new engine, they have a shift working minimum wage-esque and go with the first option of visibility thinking it's a good deal.
Financially poor, financially ignorant and time poor.
The perfect American customer.
