Expert verdict
Falls short of its own age and mileage
Like-for-like, cars this age and mileage expect about 72.2%; this one manages 64.0% — 8.2 points below. Age is a fair excuse; this is not age.
- Based on a small sample. 50 tests back this page. That is enough to publish and to index, not enough to treat the decimal places as precise — read the pattern, not the second digit.

What fails a 2004 Impian
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 Impian
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 battery 8.0% 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 lights 8.0% of tests
“malfunction indicator lamp inoperative or indicates a malfunction”
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 corrosion 6.0% 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.
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.

|---|---|---|---|
| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 30.0% | £45–95 |
