Expert verdict
Fewer problems with lamps & electrics
Lamps & electrics are 4.0% of this car’s recorded faults, against 12.2% nationally — the mirror image of the usual story on a car of this age.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 75.9% and this one manages 82.6% — 6.7 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 14% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

Where the Mazda Rx-8 is most common
Across all Rx-8 model years on record (2003–2011): 4,970 Mazda Rx-8 cars tested in a recordable postcode area, across 10,318 tests. Reading (RG) has the most, with 134 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Mazda Rx-8 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2011 Rx-8
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2011 Rx-8
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the windscreen 7.3% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
Check the coil springs 5.8% of tests
“coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
-
Check the exhaust and emissions 4.3% of tests
“catalyst emissions carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits”
Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2011 Rx-8 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £48–£163 — and 14% of those repairs are parts that cost under £30.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.

|---|---|---|---|
| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 17.4% | £45–95 |
| Tread depth below requirements of 1.6mm Tyres | Advisory | 17.4% | £45–95 |
| Rigid brake pipes excessively corroded Brakes | Advisory | 11.6% | £80–180 |
