The Carvana UX is smart and coercive. You get a (possibly artificial) time block to buy the car, which I’m sure drives conversions.

It's an amazingly high premium. I just looked up the same car I just bought last week from a used car dealer for $13.5k.

Same model, year, trim and pretty close mileage are on Caravana, listed at $19k and $21k. So a 50% premium.

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.

I think it is more likely they are targeting budget conscious people that are busy with a high paying white collar job and who don't have the time to visit dealers and haggle and want the luxury of just coming home and having the car delivered.

I agree with all that except financially poor. Most sellers I imagine would prefer their clients be wealthy (because wealthy people on average value a marginal dollar less)
