A careful inspection catches problems that a listing photo hides. Use this checklist when you view a used car, and pair it with a VIN history check and, for anything expensive, a professional pre-purchase inspection.

Exterior

  • Panel gaps that line up evenly, and paint that matches, which can reveal past accident repairs.
  • Rust around wheel arches, sills and under the car.
  • Tires: even tread wear and a matching set. Uneven wear points to alignment or suspension issues.
  • All lights and the windshield for chips or cracks.

Interior

  • Wear on the seat, pedals and steering wheel that matches the mileage.
  • Electronics: windows, locks, AC, infotainment and warning lights.
  • Signs of water damage or a musty smell, which can mean flood history.

Under the hood and the test drive

  • Oil and coolant condition, and no obvious leaks.
  • Cold start: listen for knocks and watch for smoke.
  • Test drive: brakes, steering, transmission shifts, and any vibration or pulling.

Paperwork

  • Title in the seller's name with a matching VIN and no unexpected lien.
  • Service records and a VIN history report clear of major title brands.
  • Open recalls, which you can check free at the NHTSA.
