Whether it is the same physical car is immaterial to the purchase price over time.

That simply makes no sense. One cannot argue that real incomes are falling because contemporary cars are more "expensive" than "historical" cars, and when it's pointed-out that a contemporary car is dissimilar to a historical car, claim it's "immaterial."

[Sam the Sham]

You distorted it completely.

The contemporary car costs the same that the historical car did. The price is the same. But apparently that price now takes twice as long to pay off.
