Cars are AVAILABLE for pretty much the same price.
People WANT more expensive cars.
The Volkswagen Beetle was pretty much the least expensive car on the market for its entire sales run in the United States.
The inflation-adjusted price of a Beetle in 1973 was around $12,000.
The price of a Chevrolet Spark in 2022? $13,000.
Nobody wants a Spark, though. They want an SUV. So Chevy killed the Spark.
Before Chevy discontinued the Spark you could walk onto a lot and drive away in one of the dozen or so Sparks they had rotting away in the corner for less than the price of a VW Beetle in 1973-- and the Spark was superior in every measurable way.
2023's cheapest car is the Nissan Versa. You can 100% find dealers who will part with one for less than the cost of a Beetle. It is also better than the Beetle.
