Lexus Sc430 (2004)
2004 Lexus Sc430
CarHunch analysed 293 real MOT records for the 2004 Lexus Sc430. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
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.
What to check before buying a 2004 Lexus Sc430
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 37.2% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
