Used 2020 Porsche 911 buyer's checklist

  1. Run the VIN at nhtsa.gov/recalls. 8 recalls this year — ask for proof of repairs.
  2. Engine — 3 owner reports. Cold-start the engine, listen for knocking, and watch for warning lights or hesitation on acceleration.
  3. Power Train — 2 owner reports. Test-drive through all gears, including reverse; note slipping, harsh or delayed shifts.
  4. Fuel/Propulsion System — 2 owner reports. Smell for fuel around the car and in the cabin, check that it starts easily when warm, and look at the oil dipstick for a fuel smell or rising level.
  5. Mileage to watch. Owners typically reported problems around 10 miles; ask what was repaired near that point.
  6. Before you pay: service records, a history report and an independent inspection.
