1. 1The 991 was the first 911 with electromechanical (electric) power steering in place of the old hydraulic rack; it is efficient, but many drivers find it lighter on feel than the 997 — drive one first if steering feel is a priority.
2. 2Water-cooled flat-six 911s can weep coolant with age and corrode the exposed front-mounted A/C condensers on road debris — check for coolant seepage and condenser damage.
3. 3Confirm the 991.1's safety recalls were closed: a 2014–2015 front-hood latch that might not latch (NHTSA 14V698000) and, on 2016–2017 cars, an airbag control-unit capacitor that could disable the airbags or set them off (NHTSA 19V533000); some 2014 Carreras also had a passenger-seat airbag-wiring recall (NHTSA 13V502000).

• 14V6980002014-2015
  The front-hood (bonnet) latch might not fully latch and the hood could open while driving.
• 19V5330002016-2017
  An airbag control-unit capacitor can fail, deactivating the airbags or deploying them inadvertently.
• 13V5020002014
  A passenger-seat airbag wiring fault on some cars could disable the passenger airbag.
