Every Mazda Rx-8 model year
Pass rates fall as cars age, so the only fair comparison for a 2005 car is other cars of the same age. The full run for the Mazda Rx-8:

|---|---|---|---|
| 2004 | 69.7% | 492 | 66,460 |

What this means if you are buying a 2005 Rx-8
The 2005 is a weaker year for this model, passing 3.4 points less often than the Mazda Rx-8 average. Some of that is simply age, so compare it against the 2005 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 21-year-old car fails on
A 2005 car is 21 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 2005 Mazda Rx-8 the average at test was 66,367 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 2009 at 75%, and the weakest in our data is 2005 at 68.4%. That 6.6 point spread across the model's life is why comparing a 2005 car against a newer one tells you very little.
