Don't buy a new car to get better gas mileage

Speaking of new cars, who the hell is buying them?
I have only purchased 2 new cars in twenty years and I make decent money.
The only reason I bought new is because they were new models to the US and I couldn’t buy used!
I have always been amazed at the number of new cars sold.
Then again I am not the typical American with thousands of dollars of debt.
