Expert verdict
Tyres: 2.8× the national share
Tyres make up 56.3% of everything recorded on the 2018 BMW M6, against 19.8% nationally — 36.5 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- 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 87.9% and this one manages 92.9% — 5.0 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 13% 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 BMW M6 is most common
Across all M6 model years on record (2005–2018): 2,264 BMW M6 cars tested in a recordable postcode area, across 4,150 tests. Birmingham (B) has the most, with 71 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 BMW M6 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 2018 M6
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 2018 M6
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 number plates 1.1% of tests
“registration plates does not conform to the specified requirements”
Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.
-
Check the exhaust and emissions 0.6% of tests
“catalyst emissions Lambda reading after 2nd fast idle outside 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.
-
Check the lights 0.6% of tests
“headlamp cleaning device for LED or HID headlamp inoperative”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

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.

|---|---|---|---|
| Tread depth below requirements of 1.6mm Tyres | Advisory | 8.7% | £45–95 |
| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 4.4% | £45–95 |
| Non-component advisories Nail in tyre Non-component advisories | Advisory | 3.3% | £45–95 |

| Tread depth tread pattern not visible over the whole tread area when minimum depth required is 1.0mm Tyres | Advisory | 2.7% | £45–95 |
