It might cost less to purchase a new car rather than a used car because
a) used cars are less stylish, requiring updates.
b) options cannot be chosen on a used car.
c) used cars are more likely to need repairs.
d) lack of demand drives prices down.

The best answer is C. It might cost less to purchase a new car rather than a used car because used cars are more likely to need repairs. Cars are subject to wear and tear. No matter how you take good care of a car, it will really depreciate. Used cars requires more maintenance thus requiring a lot of repairs thus giving you more costs than buying a brand new car.
