The 2005 Lexus SC430 MOT pass rate is 83.5% of its MOT tests — 11.1 points ahead of what its age and mileage predict. Suspension is the biggest single reason it fails, at 29.2% of what testers record.
Expert verdict
Suspension: 1.4× the national share
Suspension accounts for 29.2% of everything recorded on the 2005 Lexus Sc430, against 21.0% nationally — 8.2 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.
- 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 83.5% — 11.1 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 34% 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 Lexus SC430 is most common
Across all SC430 model years on record (2001–2009): 2,647 Lexus SC430 cars tested in a recordable postcode area, across 6,137 tests. Birmingham (B) has the most, with 73 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 Lexus SC430 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 SC430
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 SC430
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 shock absorbers 2.5% of tests
“shock absorbers has a serious fluid leak”
Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.
-
Check the suspension joints 2.2% 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 exhaust and emissions 1.7% 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.
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 SC430 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £30–£88 — and 34% of those repairs are parts that cost under £30.
