Every Porsche Cayman model year

Pass rates fall as cars age, so the only fair comparison for a 2011 car is other cars of the same age. The full run for the Porsche Cayman:

What this means if you are buying a 2011 Cayman

The 2011 sits close to the Porsche Cayman average, so there is no strong model-year signal either way. Judge the individual car on its own history. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.

What a 15-year-old car fails on

A 2011 car is 15 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:

  • Lights and electrical: 10.36% of all cars tested
  • Suspension: 8.65% of all cars tested
  • Tyres: 6.23% of all cars tested
  • Brakes: 6.1% of all cars tested
  • Visibility: wipers, washers, glass: 4.65% of all cars tested
  • Body, chassis and structure: 3.18% of all cars tested

That is around average, so condition and service history will tell you more than the odometer does. On a 2011 Porsche Cayman the average at test was 55,945 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.

The strongest year for this model is 2021 at 96.5%, and the weakest in our data is 2006 at 82.2%. That 14.3 point spread across the model's life is why comparing a 2011 car against a newer one tells you very little.
