The 2002 MG Zr MOT pass rate is 76.9% of its MOT tests — 4.0 points ahead of what its age and mileage predict. Brakes is the biggest single reason it fails, at 23.3% of what testers record.
Expert verdict
Body & chassis: 2.3× the national share
Body & chassis accounts for 12.7% of everything recorded on the 2002 MG Zr, against 5.6% nationally — 7.1 points above. Brakes are still the single largest share at 23.3%, but at 20.9% nationally that one is ordinary. Look underneath for corrosion near the jacking points and suspension mounts; surface rust is normal, flaking metal is not.
- 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 72.9% and this one manages 76.9% — 4.0 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 12% 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.

Every MG Zr first registered in 2002 is combined here — 2 trim and body variants in total — so the sample is as large as the DVSA data allows.
How does the 2002 MG Zr compare?
Cars of this age and mileage average 72.9%, so this figure is 4.0 points ahead of what its age and mileage predict. On a first attempt, before any retests, the figure drops to 72.2%. The median 2002 MG Zr in this dataset had covered 83,410 mi.
The most common fuel recorded here is Petrol — 89% of tests, with a 77.1% pass rate. Pass rates also shift with the test month: tests recorded October–March passed 77.0% of the time, April–September 76.9%.
The single most recorded failure item is "Joints constant velocity boot severely deteriorated", noted on 7.27% of tests.
- 949 recorded tests behind this page.
- 76.9% overall pass rate, 72.2% on a first attempt.
- Across every year of the MG Zr, the average is 75.6% — best year 2002 (76.9%), worst 2001 (73.5%).

Where the MG Zr is most common
Across all Zr model years on record (2001–2006): 3,167 MG Zr cars tested in a recordable postcode area, across 7,369 tests. Birmingham (B) has the most, with 154 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 MG Zr 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 2002 Zr
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 2002 Zr
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 corrosion 5.6% of tests
“component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength”
Look under the sills, around the jacking points and where the suspension mounts meet the body. Flaking, holed or crumbly metal fails; a brown stain on sound metal does not.
-
Check the battery 4.2% of tests
“battery(ies) insecure”
Check the battery is secure and its terminals are clean and tight — a loose battery is a fail on its own, and a weak one shows up as slow cranking on a cold morning.
-
Check the windscreen 3.7% 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.
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 2002 Zr through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £77–£208 — and 12% 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 | 13.9% | £45–95 |
