The SC430 passes its MOT just above the UK average at 82.7%, which is solid, but nearly four in ten of these cars have recorded a dangerous defect at some point—well above the comfort zone and a genuine buyer concern. The petrol-only lineup means you're not comparing fuel types, so what you see is the model's true reliability picture.

These 20-year-old cars are running at 67,000 miles on average, which is reasonable for their age, yet they're averaging nearly 20 advisories per test—a sign that wear and tear accumulates quickly on what is ultimately a high-specification, complex machine. Before committing to an SC430, pay a specialist pre-purchase inspection particular attention to the cooling system, electrics, and convertible roof mechanism, as the advisory count suggests these are common aging points.

We have limited data for the 2004 Lexus Sc430 — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
