Expert verdict
Body & chassis: 2.8× the national share
Body & chassis accounts for 15.5% of everything recorded on the 2004 Rover 45, against 5.6% nationally — 9.9 points above. Suspension is still the single largest share at 25.1%, but at 21.0% nationally that one is ordinary. Look underneath for corrosion near the jacking points and suspension mounts; surface rust is normal, flaking metal is not.
- When it fails, it costs. Only 18% 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 Rover 45 is most common
Across all 45 model years on record (2000–2006): 3,042 Rover 45 cars tested in a recordable postcode area, across 7,671 tests. Birmingham (B) has the most, with 200 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 Rover 45 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 2004 45
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 2004 45
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 6.5% 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 suspension joints 4.6% of tests
“ball joint dust cover severely deteriorated”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
-
Check the exhaust and emissions 3.4% of tests
“exhaust system has a major leak of exhaust gases”
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 2004 45 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £71–£196 — and 18% of those repairs are parts that cost under £30.
