Expert verdict
Lamps & electrics make up 18.8% of everything recorded on the 2004 Smart City Passion, against 12.2% nationally — 6.6 points above. Brakes are still the single largest share at 20.1%, but at 20.9% nationally that one is ordinary. Walk round the car with the lights on before the test: bulbs, indicators and number-plate lamps are the cheapest failures to prevent and among the most common.

Every Smart City Passion first registered in 2004 is combined here — 2 trim and body variants in total — so the sample is as large as the DVSA data allows.
Cars of this age and mileage average 72.2%, so this figure is 4.1 points ahead of what its age and mileage predict. On a first attempt, before any retests, the figure drops to 70.7%. The median 2004 Smart City Passion in this dataset had covered 70,886 mi.
Pass rates also shift with the test month: tests recorded October–March passed 78.1% of the time, April–September 74.6%.
The single most recorded failure item is "Registration plate lamp(s) inoperative in the case of multiple lamps or light sources", noted on 4.93% of tests.
Figures count every completed test on this vehicle-year in the dataset, including retests. See methodology for the exact definition.

Regions come from the postcode area recorded at the test station. Areas on region borders are assigned to the region with the majority of their population.
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
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 lights 4.9% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
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.
Check the exhaust and emissions 4.5% 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 wipers and washers 4.3% of tests
“washers provides insufficient washer liquid”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
Across the 10 items that are recorded most often on this model, the average repair comes to £24–£77 — and 54% of those repairs are parts that cost under £30.
Estimates from typical UK parts prices, weighted by how often each item appears in 507 MOT tests on this vehicle. They exclude diagnostics, retest fees and garage labour where the part is a DIY fit, and they are not figures from the DVSA dataset. Older and higher-mileage examples cost more than the average.

5 model years on record, from 2003 to 2007. Across them the pass rate runs from 73.5% to 76.7% — a spread of 3.2 points. The bar under each year is the item that failed it most often.
Colour is the pass rate on a fixed scale, so a block means the same thing on any model. Each year links to its own page with the full fault breakdown.
The raw pass rate mostly measures age. The year comparison adds the like-for-like figure, the mileage bands and the repair bill.
Closest pass rates among 2004 cars with at least 2,000 tests, so a small sample cannot flatter itself into the list. See the full rankings: best and worst MOT pass rates.

Severity is as recorded: Major and Dangerous fail the test outright; Minor and Advisory do not. Costs are estimates from typical UK parts prices — see how they are built.
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.
