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 →

Before your test

Three checks worth doing on a 2004 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.

  1. Check the lights 4.1% 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.

  2. Check the suspension joints 2.7% 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.

  3. Check the shock absorbers 2.0% 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.

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.
