Disagree. The US is enourmous, and a car is the only option outside of major metros with public transit. I encourage you to attempt to get everywhere in Tampa, FL, Dallas, TX, or Atlanta, GA without a car.
The low-mileage used car owners purchased at a higher price or buyers will use worse financing options. The dealership has an incentive to get the old models out, and the financial backing to cut interest, resulting in their being able to sell new cars for less than a low-mileage used model.
