  • Upfront cost – Used cars usually have a lower purchase price than their new counterparts.
  • Interest rates – Loans on used cars generally have higher interest rates than those on new cars. So, payments may not be that much lower than a new car.
  • Gas mileage – Newer cars generally have better gas mileage as automakers seek to improve fuel efficiency, making them well-suited for the typical St Charles commute. A car’s performance will also decline over time, decreasing fuel efficiency in used vehicles.
  • Repairs – Newer cars normally need fewer repairs than used cars and are covered under a warranty.
