Expert verdict
Emissions & leaks: 2.0× the national share
Emissions & leaks make up 11.2% of everything recorded on the 2005 BMW 730, against 5.5% nationally — 5.7 points above. Suspension is still the single largest share at 26.2%, but at 21.0% nationally that one is ordinary. A smoky diesel or a leaking joint fails on emissions more often than on wear, so ask for a recent emissions printout.
- 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 72.4% and this one manages 80.0% — 7.6 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 24% 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 730 is most common
Across all 730 model years on record (2003–2021): 15,156 BMW 730 cars tested in a recordable postcode area, across 30,754 tests. Birmingham (B) has the most, with 713 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 730 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 2005 730
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 2005 730
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 6.6% 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 suspension joints 4.8% of tests
“linkage ball joint dust cover 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 lights 3.2% of tests
“headlamp lens slightly defective”
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 it costs to get a 2005 730 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £33–£89 — and 24% of those repairs are parts that cost under £30.
