Read the Honest John Review

  • Porsche 911 (991/2) (2015 - 2019)
    New turbocharged engines have more power and torque. As impressive to drive as ever with great everyday comfort alongside superb balance in corners. Still sounds and feels like a normally aspirated 911.
  • Porsche 911 (991) (2011 - 2015)
    All-new 911 is lighter and faster. Retains familiar shape with a new interior. Six speed PDK or seven speed manual transmissions. Still the definitive sports car.
