Ok, so the graph isn't showing the price change of actual cars that people buy, buy hypothetical cars invented based in feature set.

It's kind of a weird comparison, because it makes it seem like people less in inflation-adjusted dollars, when in fact that's not true.

That's a universal problem in estimating inflation. People buy different things, and products come and go.

How do you compare a house build to 1900 standards to one build to 2020 standards? How do you compare fresh foods from the local farmer to factory-manufactured ones?

People shift preferences based on prices too. Manufactured goods started out as premium products, and now, fresh foods are increasingly a premium product.

It's an impossible problem. People either do their best, or lie with statistics, depending on the domain.
