Expert verdict
Suspension: 1.3× the national share
Suspension accounts for 27.9% of everything recorded on the 2005 Proton Impian, against 21.0% nationally — 6.9 points above. Ask for the front and rear suspension to be checked on a ramp before you buy — worn bushes and broken springs are cheap to look at and expensive to discover at test time.
- 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.
- Based on a small sample. 85 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 2005 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 2005 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 suspension joints 8.2% 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 steering 8.2% of tests
“steering rack gaiter missing or no longer prevents the ingress of dirt”
With the wheels straight, rock the steering wheel gently with the engine off — more than about an inch of free play before the wheels move is worth investigating. Split rack gaiters are cheap to replace and commonly recorded.
-
Check corrosion 7.1% 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 it costs to get a 2005 Impian through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £63–£163 — and 24% of those repairs are parts that cost under £30.
