What this means if you are buying a 2006 Mx-5

The 2006 is a weaker year for this model, passing 8.3 points less often than the Mazda Mx-5 average. Some of that is simply age, so compare it against the 2006 figure for all cars above rather than against newer examples. 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 20-year-old car fails on

A 2006 car is 20 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 a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age. On a 2006 Mazda Mx-5 the average at test was 78,170 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 97%, and the weakest in our data is 1999 at 68.3%. That 28.7 point spread across the model's life is why comparing a 2006 car against a newer one tells you very little.
