Read the Honest John Review

  • 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.
  • Porsche 911 Carrera GTS (2010 - 2012)
    The best 911 Carrera in the range, adds even more enjoyment to the great driving experience, reasonable economy considering the superb performance it offers.
